NCIt definition : A family of enzymes that catalyzes the transfer of a phosphate group from 1,3-bisphosphoglycerate
(1,3-BPG) to adenosine diphosphate (ADP) yielding 3-phosphoglycerate (3-PG) and adenosine
triphosphate (ATP) and also catalyzes the reverse reaction that transfers a phosphate
group from ATP to 3-PG yielding 1,3-BPG and ADP.;
NCIt note : Humans express two phosphoglycerate kinase proteins.;
