Did you know?
Phosphoglycerate kinase (EC 2.7.2.3) (PGK 1) 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 : 1,3-bisphosphoglycerate + ADP ⇌ glycerate 3-phosphate + ATP Like all kinases it is a transferase. … See more PGK is present in all living organisms as one of the two ATP-generating enzymes in glycolysis. In the gluconeogenic pathway, PGK catalyzes the reverse reaction. Under biochemical standard conditions, the glycolytic direction … See more Without either substrate bound, PGK exists in an "open" conformation.
