PEPCK is part of the gluconeogenesis pathway. There are 3 types of PEPCK distinguished by the energy source of the reaction which can be GTP, ATP or diphosphate. See also: Gluconeogenesis. Structural highlights E. coli GTP-driven PEPCK active site is located in a pocket at the enzyme surface. Water molecules are shown as red spheres. Mn coordination site.
