Pyruvate Carboxylase
Also written as PC.
(c) Pyruvate carboxylase carboxylates pyruvate, not PEP directly — but the classic "PEP carboxylating enzyme" referred to here is PEP carboxykinase (PEPCK) acting in reverse, or more precisely pyruvate carboxylase: Pyruvate + CO₂ + ATP → Oxaloacetate + ADP + Pi.
