phosphoenolpyruvate carboxykinase (ATP) M-CSA #51 | Phosphoenolpyruvate carboxykinase (PEPCK) catalyses first committed (rate-limiting) step in hepatic gluconeogenesis, namely the reversible decarboxylation of oxaloacetate to phosphoenolpyruvate (PEP) and carbon dioxide. This reaction can occur using either ATP or GTP as a source of the phosphate. The ATP-utilising (EC:4.1.1.49, represented here) and GTP-utilising (EC:4.1.1.32) enzymes form two divergent subfamilies, which have little sequence similarity but which retain conserved active site residues. | Defined by 8 residues: ARG:A-65LYS:A-213HIS:A-232SER:A-250LYS:A-254THR:A-255ASP:A-269ARG:A-333 | EC: 4.1.1.49 (PDB Primary Data) |
