Accepted name: phosphoglycerate mutase (2,3-diphosphoglycerate-independent)

Reaction: 2-phospho-D-glycerate = 3-phospho-D-glycerate

Other name(s): 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); iPGM; iPGAM; PGAM-i

Systematic name: D-phosphoglycerate 2,3-phosphomutase (2,3-diphosphoglycerate-independent)

Comments: The enzymes from higher plants, algae, 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.
