The histidine phosphatase superfamily is so named because catalysis centres on a conserved His residue that is transiently phosphorylated during the catalytic cycle. Other conserved residues contribute to a 'phosphate pocket' and interact with the phospho group of substrate before, during and after its transfer to the His residue. Structure and sequence analyses show that different families contribute different additional residues to the 'phosphate pocket' and, more surprisingly, differ in the position, in sequence and in three dimensions, of a catalytically essential acidic residue. The superfamily may be divided into two main branches. The larger branch 1 contains a wide variety of catalytic functions, the best known being fructose 2,6-bisphosphatase (found in a bifunctional protein with 2-phosphofructokinase) and cofactor-dependent phosphoglycerate mutase. The latter is an unusual example of a mutase activity in the superfamily: the vast majority of members appear to be phosphatases. The bacterial regulatory protein phosphatase SixA is also in branch 1 and has a minimal, and possible ancestral-like structure, lacking the large domain insertions that contribute to binding of small molecules in branch 1 members.

A	phosphoglycerate mutase (2,3-diphosphoglycerate-dependent) M-CSA #504	Phosphoglycerate mutase (EC:5.4.2.11) from vertebrates, platyhelminths, mollusks, annelids, crustaceans, insects, algae, fungi, yeast and some bacteria (particularly Gram-negative) interconverts 2-phosphoglycerate and 3-phosphoglycerate via a transiently phosphorylated active site histidine. This histidine is phosphorylated by a 2,3-diphosphoglyerate cofactor. The enzyme has no requirement for metal ions and also catalyses, slowly, the reactions of EC 5.4.2.4, bisphosphoglycerate mutase.
