Description

The activation of de novo pyrimidine biosynthesis is a requirement for cell proliferation in tumor tissues. The carbamoyl phosphate synthetase (CPSase) catalyses the rate-limiting step of the synthetic pathway. CPSase refers to one catalytic activity of the multifunctional protein CAD that catalyses the first three steps of the pathway.
