| Description: The formation of N-carbamoyl-L-aspartate from carbamoyl phosphate and aspartate is the first committed step in a series of reactions that leads to synthesis of pyrimidine nucleotides, so control at or near this point is essential. In prokaryotes, the aspartate carbamoyltransferas e (ATCase) is regulated; in most eukaryotes, regulation is on the preceding step, catalyzed by carbamoyl phosphate synthetase II.
