||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 22.214.171.124 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.
