3-phosphoglycerate kinase
Phosphoglycerate kinase (PGK) is an enzyme that catalyzes the reversible transfer of a phosphate group from 1,3-bisphosphoglycerate (1,3-BPG) to ADP producing 3-phosphoglycerate (3-PG) and ATP. Like all kinases it is a transferase.
Chemical equation
![1,3BPG + ADP \rightleftharpoons 3PG + ATP
