NCIt definition : CAD protein (2225 aa, 293 kDa) is encoded by the human CAD gene. This protein is
involved in pyrimidine biosynthesis.;
NCIt note : CAD protein forms a homohexamer and has four enzymatic activities: glutamine amidotransferase,
carbamoyl phosphate synthase, aspartate carbamoyltransferase and dihydroorotase. The
activities of the CAD protein have IUBMB designations of EC 6.3.5.5, EC 2.1.3.2, and
EC 3.5.2.3. (UniProt);
