Question

What is the function of PEP carboxylase?

Answer 1

PEP Carboxylase:

1. It is a carboxylase enzyme that catalyzes the binding of 1 carbon dioxide molecule to the 3-C compound phosphoenolpyruvate, resulting in the creation of the four-carbon complex oxaloacetate.
2. It is the first enzyme in the Hatch Slack pathway's carbon fixing or C_4.
3. It catalyzes the conversion of phosphoenolpyruvate (PEP) to the 4C acid, oxaloacetic acid (OAA), by adding CO₂.
