PEPCK is part of the gluconeogenesis pathway[1]. There are 3 types of PEPCK distinguished by the energy source of the reaction which can be GTP, ATP or diphosphate. Structural highlights E. coli GTP-driven PEPCK is located in a pocket at the enzyme surface[2]. Water molecules shown as red spheres. . .
