Accepted name:
phosphoglycerate mutase (2,3-diphosphoglycerate-independent)
Other names:
cofactor independent phosphoglycerate mutase
2,3-diphosphoglycerate-independent phosphoglycerate mutase
phosphoglycerate phosphomutase [ambiguous]
phosphoglyceromutase [ambiguous]
monophosphoglycerate mutase [ambiguous]
monophosphoglyceromutase [ambiguous]
GriP mutase [ambiguous]
PGA mutase [ambiguous]
Systematic name:
D-phosphoglycerate 2,3-phosphomutase (2,3-diphosphoglycerate-independent)




The enzymes from higher plants, algae, some fungi, nematodes, sponges, coelenterates, myriapods, arachnids, echinoderms, archaea and some bacteria (particularly Gram-positive) have maximum activity in the absence of 2,3-bisphospho-D-glycerate. cf. EC phosphoglycerate mutase (2,3-diphosphoglycerate-dependent). The enzyme contains two Mn2+ (or in some species two Co2+ ions). The reaction involves a phosphotransferase reaction to serine followed by transfer back to the glycerate at the other position. Both metal ions are involved in the reaction.
