Description
PhosphoglyceRate kinase (EC 2.7.2.3) (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. PGK is a major enzyme used in glycolysis, in the first ATP-geneRating step of the glycolytic pathway. In gluconeogenesis, the reaction catalyzed by PGK proceeds in the opposite direction, geneRating ADP and 1,3-BPG.

Applications
3-Phosphoglyceric Phosphokinase generates ATP by catalyzing the transfer of a phosphate group from 1,3-diphosphoglycerate to ADP. 3-Phosphoglycerate Phosphokinase is used to study glycolysis and gluconeogenesis. It has also been used to study low molecular weight GTP-binding proteins and mechanisms of inhibition of glyceraldehyde-3-phosphate dehydrogenase. The enzyme has been used in the assay of glyceraldehyde-3-phosphate dehydrogenase.
