Phosphoglycerate kinase
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. After both the triose and nucleotide substrates are bound to the N- and C-terminal domains, respectively, an extensive hinge-bending motion occurs, bringing the domains and their bound … See more Phosphoglycerate kinase (PGK) deficiency is an X-linked recessive trait associated with hemolytic anemia, mental disorders and myopathy in humans, depending on form – there exists a hemolytic form and a myopathic form. Since the trait is X-linked, it is usually fully … See more Overview PGK is found in all living organisms and its sequence has been highly conserved throughout … See more The enzyme is activated by low concentrations of various multivalent anions, such as pyrophosphate, sulfate, phosphate, and citrate.

WebPhosphoglycerate kinase (PGK) is a glycolytic enzyme that is well conserved among the three domains of life. PGK is usually a monomeric enzyme of about 45 kDa that catalyses one of the two ATP-producing reactions in the glycolytic pathway, through the conversion of 1,3-bisphosphoglycerate (1,3BPGA) to 3-phosphoglycerate (3PGA). WebIn enzymology, a phosphoglycerate kinase (GTP) ( EC 2.7.2.10) is an enzyme that catalyzes the chemical reaction GTP + 3-phospho-D-glycerate GDP + 3-phospho-D-glyceroyl phosphate Thus, the two substrates of this enzyme are GTP and 3-phospho-D-glycerate, whereas its …
