Bootstrap probability of a cluster is only shown at the root node of the cluster when the value is equal to or greater than 50%. Isotopic labeling experiments have confirmed that this reaction proceeds through a glucose 1,6-bisphosphate intermediate. PGAM1 catalytic activity is based on histidine phosphorylation. 7). The structures of Leishmania mexicana cofactor-independent phosphoglycerate mutase (Lm iPGAM) crystallised with the substrate 3-phosphoglycerate at high and low cobalt concentrations have been solved at 2.00- and 1.90-A resolutions. Crystal structure of the complex with 2-phosphoglycerate. Many affected patients also have tubular aggregates in the muscle biopsy. This reaction is linked to the conversion of NADH to NAD by glyceraldehyde-3-phosphate dehydrogenase (Ga3PD) and phosphoglycerate kinase (PGK): The fail in absorbance at 340 nm, as NADH is oxidised, is measured. Phosphoglycerate mutase 1 (PGAM1) plays a pivotal role in cancer metabolism and tumor progression via its metabolic activity and interaction with other proteins like α-smooth muscle actin (ACTA2). Click on genes, proteins and metabolites below to link to respective articles. It cata-lyzes the isomerization of 3-pho sphoglycerate into downstream glycolytic product 2-phosphoglycerate with intermediate product formation of 2, 3-bisphosphoglycerate (2, 3-BPG) (Figure 1). Patients with McArdle disease experience a “second wind” phenomenon. chemical logic of Conversion of 3-Phosphoglycerate to 2-Phosphoglycerate. Using phosphoglycerate mutase Kinetic studies of the phosphoglycerate mutase reaction suggested the likelihood of a ping-pong mechanism (18), Residual glycolysis is sufficient to support normal aerobic capacity so there is no evidence of substrate-limited oxidative metabolism. Fig. Phosphoglycerate mutase 5 (PGAM5), a mitochondrially-localized serine/threonine-protein phosphatase, functions as a novel inducer of necroptosis. Phosphoglycerate mutase family member 5 (PGAM5) is a serine/threonine phosphatase that has been localized to both inner and outer mitochondrial membranes. (16) and Kappel et al. [8], The catalyzed mutase reaction involves two separate phosphoryl groups and the ending phosphate on the 2-carbon is not the same phosphate removed from the 3-carbon. Glycolysis is a 10-step process that invests energy in the initial stages only to recover greater amounts of energy in the final steps. We suggest that the ability to generate PGAM5 complexes that have a wide range of phosphatase activities will facilitate screens to identify small molecules that modulate the phosphatase activity of PGAM5. Muscle phosphoglycerate mutase deficiency (PGAMD) is a metabolic myopathy characterised by exercise-induced cramp, myoglobinuria, and presence of tubular aggregates in the muscle biopsy. Moreover, the presence of the last glycine of the RHG motif is not an absolute prerequisite for these enzymes and is frequently replaced with alanine. Acta Neuropathol 2009; 117:723. Joshi PR, Knape M, Zierz S, Deschauer M. Phosphoglycerate mutase deficiency: case report of a manifesting heterozygote with a novel E154K mutation and very late onset. The histidine-bound phosphate is donated to carbon-2 of 3-phosphoglycerate, then the phosphate of carbon-3 is removed by the histidine, leaving 2-phosphoglycerate and phosphohistidine. This short helix contributes to active site formation by contacting His108 and Ser51. Such similarities make such enzymes promising drug target in parasitic nematodes. [citation needed]. Every step in this metabolic pathway is essential to the ultimate production of energy. [citation needed] This presents as a metabolic myopathy and is one of the many forms of syndromes formerly referred to as muscular dystrophy. Bacterial proteins are colored magenta (α‐proteobacteria), orange (β‐proteobacteria), red (γ‐proteobacteria), blue (δ/ε‐proteobacteria), cyan (actinobacteria), green (cyanobacteria), ruby (bacteroidetes/ chlorobium), and other colors (others). 8). Symptoms are more likely to occur during intense isometric exercise (lifting heavy weights) or during less intense but sustained dynamic exercise (walking up stairs). Hence, by modulating the ratio between these two metabolites, PGAM could coordinate biosynthetic processes that branch from glycolysis (Fig. Phosphoglycerate mutase (PGM) catalyzes the isomerization of 3-phosphoglycerate and 2-phosphoglycerate in glycolysis and gluconeogenesis. Of the eight genetically characterized African American patients, seven were homozygous for a W78X nonsense mutation in exon 1, and one was compound heterozygous for this mutation and a novel missense mutation, suggesting a founder effect (35). The failure of blood lactate to increase in response to exercise is a useful diagnostic test and can be used to differentiate muscle glycogenoses from disorders of lipid metabolism, such as carnitine palmitoyl transferase II deficiency and very long chain acyl-CoA dehydrogenase deficiency, which also cause muscle cramps and myoglobinuria. It catalyzes the internal transfer of a phosphate group from C-3 to C-2 which results in the conversion of 3-phosphoglycerate (3PG) to 2-phosphoglycerate (2PG) through a 2,3-bisphosphoglycerate intermediate. Serine and all the other 13 amino acid residues involved in the catalytic function of iPGM are highly conserved. PGM is an isomerase enzyme, effectively transferring a phosphate group (PO4 ) from the C-3 carbon of 3-phosphoglycerate to the C-2 carbon forming 2-phosphoglycerate. This trend in SixA distribution may be correlated with the distribution of HPt proteins. All six enzyme defects cause symptoms and signs of muscle energy impairment similar to those of the types V and VII GSD. The enzyme is found in organisms as simple as yeast through Homo sapiens and its structure is highly conserved throughout. It is responsible for the catalytic synthesis of 2,3-Bisphosphoglycerate (2,3-BPG) from 1,3-bisphosphoglycerate.BPGM also has a mutase and a phosphatase function, but these are much less active, in contrast to its glycolitic cousin, phosphoglycerate mutase (PGM), which favors these two … Bisphosphoglycerate mutase (BPGM) is an enzyme unique to erythrocytes and placental cells. A similar ultrastructural pattern of glycogen excess is found in all disorders of glycogenolysis and glycolysis. Mutations in the genes encoding the enzymes have been identified in all four of these disorders. 2B). EMG and nerve conduction were normal. Based on these distances, an NJ tree was constructed for all of the sequences included in the alignment. Fig. 1bq3B:3-189 1bq4B:3-189 1riiA:6-190 Marc C. Patterson, in Swaiman's Pediatric Neurology (Sixth Edition), 2017. Two distinct types of PGM exist in nature, one that requires 2,3-bisphosphoglycerate as a cofactor (dPGM), and another that does not (iPGM), as it is structurally distinct and possesses different mechanisms of action. 1bif :251-398 1k6mB:253-400 1c80A:253-400 (17) showed that the three activities are not separated during purification procedures. 1c7zA:253-400 1fbtB:253-400 1c81A:253-400, Phosphoglycerate mutase (PGM) is any enzyme that catalyzes step 8 of glycolysis. 1.2) (Hitosugi et al., 2012). Patients often experience acute muscle necrosis and myoglobinuria after exercise, which, if severe, can cause acute renal failure. J Biol Chem. 7. Phosphoglycerate mutase deficiency (PGAMD—glycogen storage disease, type X) has been associated in adults with myalgia, cramps, and myoglobinuria after exercise. Figure 39.6. Utilizing data derived from the various genome sequence projects, we identified SixA homologs following database searches with BLAST (Altschul et al., 1990) and PSI‐BLAST (Altschul et al., 1997) at the National Center for Biotechnology Information (NCBI) site. Phosphoglycerate mutases (PGMs) catalyze the isomerization of 2- and 3-phosphoglycerates and are essential for glucose metabolism in most organisms. Priya S. Kishnani, Yuan-Tsong Chen, in Emery and Rimoin's Principles and Practice of Medical Genetics, 2013. Dephosphorylation of the enzyme histidine actuates a local allosteric change in enzyme configuration which now aligns the substrates 3-C phosphate group with enzyme active site histidine and facilitates phosphate transfer returning the enzyme to its initial phosphorylated state and releasing product 2-phosphoglycerate. In this mechanism Mn 2+ ions facilitate the transfer of the substrate's phosphate group to Ser62 to form a phosphoserine intermediate. In the E. coli SixA structure, Gly9 contacts with Leu23, which is strictly limited to leucine or isoleucine in the RHG phosphatases. Nematodes possess the iPGM form, whereas mammals have dPGM. Purpose: Necroptosis is an important form of cell death following myocardial ischemia/reperfusion (I/R) and phosphoglycerate mutase 5 (PGAM5) functions as the convergent point for multiple necrosis pathways. [15] An unusual pathologic feature of PGAM deficiency is the association with tubular aggregates. [citation needed] PGAM1 deficiency affects the liver, while PGAM2 deficiency affects the muscle. ... • Mechanism of reoxidizing NADH in fermenting microorganisms In contrast, the iPGM class is independent of 2,3-bisphosphoglycerate and catalyzes the intramolecular transfer of the phosphate group on monophosphoglycerates using a phosphoserineintermediate. Phosphoglycerate mutase does not readily release glycerate-2,3-P2 (19). In contrast to proteobacteria, we failed to find any candidate within most of genera of Firmicutes and other bacteria families (Fusobacteria, Planctomicesm, Chlamydiae, Thermotogae, and Chloroflexi). Certain salts, such as KCl, are known to be competitive inhibitors in respect to 2-phosphoglycerate and mutase activity. These archaeal HPt proteins are chemotaxis sensor kinases rather than ArcB homologs. The presence or absence of the insertion at loop β3‐H5 represents one determinant for detecting SixA homolog candidates. Anionic molecules such as vanadate,[12] acetate, chloride ion, phosphate, 2-phosphoglycolate, and N-[tris(hydroxymethyl)methyl-2-amino]ethanesulfonate are known inhibitors of the mutase activity of dPGM. Serum CK level was increased between attacks. 1. Two copies of SixA homologs of three species in α‐proteobacteria are separated into two groups that form roughly two clusters, while two copies of SixA homologs of Hahella chejuensis in γ‐proteobacteria are distantly separated from each other and from any copy of α‐proteobacteria. Since it is a reversible reaction, it is not the site of major regulation mechanisms or regulation schemes for the glycolytic pathway. Moreover, SixA seems to be rare in archaea. This aliphatic residue may be characteristic of SixA and is not conserved in Ais, as is the case with Asp18 and Arg21. The three-dimensional structure of B. anthracis PGM is composed of two structural and functional domains, the … Michio Hirano MD, in Neurobiology of Disease, 2007. Lactate dehydrogenase M subunit deficiency has been reported in three families with exertional myoglobinuria. The mechanism of phosphoglycerate mutase involves creation of 2,3-bisphosphoglycerate by a phosphorylated histidine in the enzyme. In the cofactor-dependent enzyme's initial state, the active site contains a phosphohistidine complex formed by phosphorylation of a specific histidine residue. [§ 1]. Phosphoglycerate mutase (PGM) is any enzyme that catalyzes step 8 of glycolysis. [9] When 3-phosphoglycerate enters the active site, the phosphohistidine complex is positioned as to facilitate transfer of phosphate from enzyme to substrate C-2 creating a 2,3-bisphosphoglycerate intermediate. One exception is Ais, which lacks this insertion. In humans the PGAM2 gene which encodes this enzyme is located on the short arm of chromosome 7. Each genus name is assigned + or − to indicate the presence or absence, respectively, of a SixA homolog. 1ebbA:2-151 2bifA:251-398 3bifA:251-398 Numbers at the beginning and end of each sequence indicate amino acid position of the protein. 3 | CATALYTIC MECHANISM OF PGAM1 PGAM1 is a brain isoform of phosphoglycerate mutase. There are a total of three reactions dPGM can catalyze: a mutase reaction resulting in the conversion of 3PG to 2PG and vice versa,[4][5] a phosphatase reaction creating phosphoglycerate from 2,3-bisphosphoglycerate,[6][7] and a synthase reaction producing 2,3-bisphosphoglycerate from 1,3-bisphosphoglycerate similar to the enzyme bisphosphoglycerate mutase[citation needed]. Every step is catalyzed by one or more enzymes that enhance the rate of the given reaction.

Muscle glycogen levels may be normal in the disorders affecting terminal glycolysis, and definite diagnosis is made by assaying the muscle enzyme activity. 2,3-bisphosphoglycerate is required a cofactor for dPGM. Reaction mechanism Phosphoglucomutase affects a phosphoryl group shift by exchanging a phosphoryl group with the substrate. Following alignment of the collected sequences by MAFFT (Katoh et al., 2002, 2005), alignment was slightly modified by visual inspection. However, intense debate exists regarding the effect of PGAM5 on I/R-related cardiomyocyte death. Deficiency of phosphoglycerate mutase causes glycogen storage disease type X, a rare autosomal recessive genetic disorder with symptoms ranging from mild to moderate; is not thought life-threatening and can be managed with changes in lifestyle. An electron micrograph shows focal excess of electron-dense (dark) glycogen particles in a subsarcolemmal zone (arrowheads) and within the cytoplasm. 6. Hasan O. Akman, ... Salvatore DiMauro, in Neuromuscular Disorders of Infancy, Childhood, and Adolescence (Second Edition), 2015. Phosphoglycerate mutase (PGM) is an enzyme that catalyzes step 8 of glycolysis. Kinetic and structural studies have provided evidence that indicate dPGM and bisphosphoglycerate mutase are paralogous structures. Like phosphoglucomutase (20), it does not form free enzyme with each turnover but regenerates E- P. In contrast, bisphosphoglycerate synthase is limited by the rate of phosphorylation (6). The symptoms are an intolerance to physical exertion or activity, cramps and muscle pain. Each sequence is indicated by the source name and the GI number in NCBI. Six additional enzyme defects produce muscle glycogenoses, namely, deficiencies in phosphoglycerate kinase, phosphoglycerate mutase, lactate dehydrogenase, fructose-1,6-bisphosphate aldolase A, pyruvate kinase, and β-enolase. Serum creatine kinase (CK) levels are increased between episodes of myoglobinuria. Archaeal SixA homologs are included in the bacterial SixA families. The mb-isozyme is found in cardiac and skeletal muscle and the bb-type is found in the rest of tissues. Isolated myopathy with intolerance of vigorous exercise, cramps, and myoglobinuria has been reported in a few patients with PGK deficiency. The rat was isolated by the procedure of Scopes (1977) with the modification that PGM was selectively eluted from a final CM-Sephadex column with 1 mM NaI. Aromatic (W, F, Y) residues are colored red, aliphatic (V, L, I, M) pink, acidic and amide (D, E, N, Q) blue, basic (K, R, H) green, cysteine (C) yellow, and others (S, T, P, G, A) gray. [11] While all three isozymes may be found in any tissue, the above distributions are based on prevalence in each. In mammals, the enzyme subunits appear to be either a muscle-derived form (m-type) or other tissue (b-type for brain where the b-isozyme was originally isolated). The ability to purify different PGAM5 complexes and to characterize their kinetic properties will enable detailed biophysical studies of the quaternary structures of the various PGAM5-containing complexes. The full-length cDNA encoding the M-subunit has been cloned,102 and the entire gene encoding PGAM-M has been isolated, sequenced,103 and mapped to chromosome 7p12–7p13.104,105, About 15 patients have been reported, most of them African Americans.106,107 All African American patients harbor one common nonsense mutation (W78X), suggesting a founder effect.107 Different mutations have been found in Italian families,108,109 in a Japanese family,110 and in a Pakistani patient107,111 Despite the abundance of PGAM in muscle, we and others have observed exercise intolerance in heterozygous carriers.107,110,112. Myophosphorylase deficiency (McArdle disease, type V), muscle phosphofructokinase deficiency (Tarui's disease, type VII), phosphoglycerate mutase deficiency (type X), and lactate dehydrogenase A deficiency (type XI) have similar presenting myopathic features: exercise intolerance with increased fatigue, myalgia, and painful muscle contractions relieved by rest. The Wb-iPGM isoform-1 gene encodes an ORF of 515 amino acids and is found to share 96.0% amino acid sequence identity with the iPGM of O. volvulus. The evolutionary distance between every pair of aligned sequences was calculated as the maximum likelihood (ML) estimate (Felsenstein, 1996) using the JTT model (Jones et al., 1992) for the amino acid substitutions. Abstract: Phosphoglycerate mutase 1 (PGAM1) is an important enzyme that catalyzes the reversible conversion of 3-phosphoglycerate and 2-phosphoglycerate during the process of glycolysis. Muscle Nerve 2013; 47:138. Phosphoglycerate mutase (PGM) catalyzes the isomerization of 3-phosphoglycerate and 2-phosphoglycerate in glycolysis and gluconeogenesis. The statistical significance of the NJ tree topology was evaluated by bootstrap analysis (Felsenstein, 1985) with 1000 iterative tree constructions. Two distinct types of PGM exist in nature, one that requires 2,3-bisphosphoglycerate as a cofactor (dPGM), and another that does not (iPGM), as it is structurally distinct and possesses different mechanisms of action. [3], PGM is an isomerase enzyme, effectively transferring a phosphate group (PO43−) from the C-3 carbon of 3-phosphoglycerate to the C-2 carbon forming 2-phosphoglycerate. They catalyze the internal transfer of a phosphate group from C-3 to C-2 which results in the conversion of 3-phosphoglycerate (3PG) to 2-phosphoglycerate (2PG) through a 2,3-bisphosphoglycerate intermediate. About 95% of PGAM enzymatic activity in skeletal muscle is attributable to the MM homodimer. Phosphoglycerate mutase (PGM) is the specific homotetramer enzyme that catalyzes step 8 of glycolysis transfering the ph… The high similarity in catalytic properties shown by the enzymes indicates that a single enzyme inhibitor would probably be effective against all nematode enzymes, which supports the development of iPGM as a promising drug target in parasitic nematodes. Phosphoglycerate mutase 1 (PGAM1) is a glycolytic enzyme that importantly coordinates glycolysis, pentose phosphate pathway (PPP) flux and serine biosynthesis in cancer cells and hence gains increasing interest of inhibitor discovery. 8. [13] Both phosphate and 2-phosphoglycolate are competitive inhibitors of mutase activity in respect to the substrates 2-phosphoglycerate and 2,3-bisphosphoglycerate.[14]. The mm-type is found mainly in smooth muscle almost exclusively. As reported previously (Rigden, 2003), SixA forms a monophyletic cluster distant from other families, including the Ais family. The bar under the tree corresponds to 0.1 amino acid substitutions/site. Normal mature muscle contains predominantly the MM homodimer.101 Liver, kidney, and brain contain mainly the BB form, and heart contains all three dimer types, MM, BB, and MB. Indeed, the SMART database (Letunic et al., 2006; Schultz et al., 1998) contains a small number (20) of archaeal HPt proteins out of a total of 1444 HPt proteins that contain 1380 bacterial proteins. Only few PGAM1 inhibitors have been reported and the molecular potency remains very limited. The properties and kinetics of the 2,3-diphosphoglycerate-dependent phosphoglycerate mutases are discussed. Phosphoglycerate mutase (PGM) is any enzyme that catalyzes step 8 of glycolysis. Another important enzyme recently found to regulate glycolytic branching is PGAM (Hitosugi et al., 2012). In detail, 3PG was found to inhibit the PPP enzyme 6-phosphogluconate dehydrogenase (6PGDH) and 2PG to activate PHGDH (Hitosugi et al., 2012). Muscle biopsy was normal in most patients, but diffuse or patchy glycogen accumulation was seen in a few cases (Figure 39.6), and about one-third of patients had tubular aggregates, a finding not shared by any other glycolytic disorder and whose pathogenesis remains obscure. Permanent weakness is rare. Multiple alignment of SixA homologs with some well‐characterized RHG phosphatases. Phosphoglycerate mutase deficiency (glycogenosis type X). Thus, these two residues are determinant residues for SixA homologs. An unrooted NJ tree of SixA and some well‐characterized RHG phosphatases. Species that contain two copies of SixA homologs are marked (2) and include α‐proteobacteria Mesorhizobium loti MAFF 303099, Rhizobium etli CFN 42, and Sinorhizobium meliloti 1021 and γ‐proteobacteria Hahella chejuensis KCTC 2396. The a ctive site residue, His-10, is the nucleophilic histidine that participates in dPGM's catalytic mechanism and is phosphorylated to phosphohistidine, occupying 0.28Å in its active conformation. Phosphoglycerate mutase deficiency (GSDX) is a rare and benign muscle glycogenosis that occurs due to a partial block of terminal glycolysis. Essential for rapid growth and for sporulation. 4pgmB:3-189 3pgmB:3-189 1qhfA:3-189 1.2). In this chapter, we describe methods for obtaining both multimeric and dimeric complexes of PGAM5 and for characterizing their kinetic properties.

There is no specific treatment. process. BPGM; PFKFB1; PFKFB2; PFKFB3; PFKFB4; PGAM1; PGAM2; Cycle exercise responses in two patients were markedly different from those seen in McArdle disease: the PGAM patients had virtually normal cycle exercise and oxidative capacity, no second wind, and no improvement of their exercise capacity with lipid or lactate supplementation.113, Stefano Sainas, ... Marco L. Lolli, in Annual Reports in Medicinal Chemistry, 2018. [6] Both enzymes are contained in the superfamily that also contains the phosphatase portion of phosphofructokinase 2 and prostatic acid phosphatase. Phosphoglycerate mutase deficiency with tubular aggregates in a patient from Panama. Up to 2007, 26 families had been reported. In the subsequent phosphotransferase part of the reaction, the phosphate group is transferred from Ser62 to the O2 or O3 positions of the reoriented glycerate to yield the PGA product. Mark Layton, David Roper, in Dacie and Lewis Practical Haematology (Twelfth Edition), 2017. In Streptococcus suis, phosphoglycerate mutase binds to host fibronectin and collagen type I . Existing as a dimer, the enzyme then has 3 isozymes depending on which subunit forms makeup the whole molecule (mm, bb or mb). Sequence data with significant similarity to E. coli SixA were collected following database searches using BLAST with E‐value <0.001 and PSI‐BLAST employing five iterations with E‐value <0.005 at the NCBI site (http://www.ncbi.nlm.nih.gov/blast/psiblast.cgi). Both Asp18 and Arg21 are located at the C‐terminal region of loop β1‐H2 containing helix H1 (Fig. This study reports the production, structure, and molecular dynamics analysis of Bacillus anthracis cofactor-independent PGM (iPGM). A patient with PGAMD who experienced muscle cramps on forearm ischemic exercise testing was protected from cramps by dantrolene, suggesting that cramps in this disease reflect excessive calcium release from the sarcoplasmic reticulum relative to calcium reuptake capacity. It's the enzyme that catalyzes the conversion of 3-phosphoglycerate to 2-phosphoglycerate. Allosteric regulation is considered to be an innovative strategy to discover a highly selective and potent inhibitor targeting PGAM1. Salameh J, Goyal N, Choudry R, et al. We searched putative homologs of E. coli SixA from bacteria, archaeal, fungi, and yeast. The alignment reveals that Asp18 and Arg21 are well conserved in SixA homologs but not within others. [2] This class of PGM enzyme shares the same superfamily as alkaline phosphatase. PGAM catalyzes the conversion of 3PG into 2-phosphoglycerate (2PG) (Fig. This study reports the production, structure, and molecular dynamics analysis of … Nine of the 13 patients described with this disorder have been African Americans. These metabolites have been recently shown to modulate two important biosynthetic branches of glycolysis: the oxidative arm of the PPP and the serine biosynthesis pathway. In work by Dhamodharan et al.,78 an analysis of partial genomic and amino acid sequences and the phylogenetic tree of W. bancrofti (Wb-iPGM), the major causative agent of human lymphatic filariasis, indicated that this gene, apart from being a potential drug target, could also provide diagnostic, taxonomical, and evolutionary markers.
