  • Title: Identification of the junction between the glutamine amidotransferase and carbamyl phosphate synthetase domains of the mammalian CAD protein.
    Author: Maley JA, Davidson JN.
    Journal: Biochem Biophys Res Commun; 1988 Aug 15; 154(3):1047-53. PubMed ID: 2900634.
    Abstract:
    The hamster CAD gene encodes a protein that catalyzes the first three steps of pyrimidine biosynthesis. We have sequenced a portion of a CAD cDNA and determined the location of the carbamyl phosphate synthetase II coding region. Subdomains coding for the glutamine hydrolyzing and carbamyl phosphate synthesizing functions have been identified through their high degree of similarity to carbamyl phosphate synthetase genes from a variety of organisms. The proline-rich junction between the glutaminase and synthetase domains, however, does not appear to be conserved among carbamyl phosphate synthetases.
