FunctionInterconversion of 3- and 2-phosphoglycerate with 2,3-bisphosphoglycerate as the primer of the reaction. Can also catalyze the reaction of EC 188.8.131.52 (synthase) and EC 184.108.40.206 (phosphatase), but with a reduced activity.
Tissue specificityIn mammalian tissues there are two types of phosphoglycerate mutase isozymes: type-M in muscles and type-B in other tissues.
Involvement in diseaseDefects in PGAM2 are the cause of glycogen storage disease type 10 (GSD10) [MIM:261670]. A metabolic disorder characterized by myoglobinuria, increased serum creatine kinase levels, decreased phosphoglycerate mutase activity, myalgia, muscle pain, muscle cramps and excercise intolerance.
Sequence similaritiesBelongs to the phosphoglycerate mutase family. BPG-dependent PGAM subfamily.
