phosphoglycerate mutase activity
Definition
Target type: molecularfunction
Catalysis of the reaction: (2R)-2-phosphoglycerate = (2R)-3-phosphoglycerate. [RHEA:15901]
Phosphoglycerate mutase (PGM) activity catalyzes the reversible isomerization of 3-phosphoglycerate (3PG) to 2-phosphoglycerate (2PG). This reaction is a crucial step in glycolysis, the central metabolic pathway for energy production in most organisms. The enzyme utilizes a unique mechanism involving a histidine residue within its active site. This histidine residue is initially phosphorylated by 2PG, forming a phosphohistidine intermediate. This intermediate then transfers the phosphate group to 3PG, generating 2PG and regenerating the active enzyme. PGM activity is essential for glycolysis, as it allows for the conversion of 3PG, a substrate that is not readily utilized by subsequent enzymes, to 2PG, which can be further metabolized in the glycolytic pathway. The precise mechanism and regulation of PGM activity can vary depending on the specific enzyme and its cellular context. However, the overall function of PGM is to facilitate the efficient and reversible interconversion of 3PG and 2PG, ensuring the smooth operation of glycolysis and energy production.'
