Carbamoyl phosphate synthetase II is an enzyme that catalyzes the reactions that produce carbamoyl phosphate in the cytosol (as opposed to type I, which functions in the mitochondria).

In pyrimidine biosynthesis, it catalyzes the following reaction: Gln + CO₂ + 2 ATP + H₂O → carbamoyl phosphate + Glu + 2 ADP + P_i

It is activated by ATP and PRPP and it is inhibited by UMP (Uridine monophosphate, the end product of the pyrimidine synthesis pathway).

CPSII is a cyttosolic enzyme used to make purines! not i mean pyramidines Both CPSI and CPSII do not require Biotin as a coenzyme, as seen with most carboxylation reactions.

It is one of the three enzyme functions coded by the CAD gene. It is classified under EC 6.3.5.5.
