Function

Phosphoenolpyruvate carboxylase (PEPC) catalyzes the addition of bicarbonate to phosphoenolpyruvate to form oxaloacetate and phosphate. PEPC is part of the carbon fixation process in plants^[1]. PEPC is inhibited by aspartate, fumarate and malonate.

Structural highlights

Maze PEPC contains an ^[2]. . Water molecules shown as red spheres.
