Bisphosphoglycerate Mutase

This enzyme [EC 5.4.2.4] (also known as bisphosphoglyc-erate synthase, diphosphoglycerate mutase, and glycer-ate phosphomutase) catalyzes the reversible interconversion of 3-phospho-d-glyceroyl phosphate to 2,3-bisphospho-d-glycerate. The "cofactor" for this enzyme is 3-phosphoglyceroyl phosphate. In the reaction scheme, the enzyme is phosphorylated by this "cofactor" to yield a phosphoenzyme and 3-phosphoglycerate. The latter compound is then rephosphorylated by the enzyme to yield 2,3-bisphosphoglycerate, but this reaction is slowed down by dissociation of 3-phosphoglycerate from the enzyme, which is therefore more active in the presence of added 3-phosphoglycerate.
