IntEnz Enzyme Nomenclature


Accepted name:
phosphoglucomutase (α-D-glucose-1,6-bisphosphate-dependent)
Other names:
glucose phosphomutase [ambiguous]
phosphoglucose mutase [ambiguous]
Systematic name:
α-D-glucose 1,6-phosphomutase



Maximum activity is only obtained in the presence of α-D-glucose 1,6-bisphosphate. This bisphosphate is an intermediate in the reaction, being formed by transfer of a phosphate residue from the enzyme to the substrate, but the dissociation of bisphosphate from the enzyme complex is much slower than the overall isomerization. The enzyme also catalyses (more slowly) the interconversion of 1-phosphate and 6-phosphate isomers of many other α-D-hexoses, and the interconversion of α-D-ribose 1-phosphate and 5-phosphate. cf. EC, phosphoglucomutase (glucose-cofactor). Formerly EC
