ⓘ Phosphoglycerate kinase

Phosphoglycerate kinase is an enzyme that catalyzes the reversible transfer of a phosphate group from 1.3-bisphosphoglycerate to ADP producing 3-phosphoglycerate and ATP:

1.3-bisphosphoglycerate + ADP ⇌ glycerate 3-phosphate + ATP

As with all kinase is a transferase. PGK is a major enzyme used in glycolysis, the first ATP-generating step of glycolysis. In gluconeogenesis, the reaction is catalyzed by PGK proceeds in the opposite direction, forming ADP and 1.3-BPG.

In humans, two isozymes of PGK have been so far identified, PGK1 and PGK2. Isoenzymes are 87-88% identical to the amino acid sequence identity, and although they are structurally and functionally similar, they have different localizations: PGK2, encoded by an autosomal gene, is unique to meiosis and postmeiotic spermatogenic cells, while PGK1, encoded in the X chromosome, is expressed ubiquitously in all cells.
