The synthesis of N-carbamoyl L-aspartate from carbamoyl phosphate and L-aspartate is catalyzed by the aspartate carbamoyltansferase activity of cytosolic trifunctional CAD (carbamoyl-phosphate synthetase 2, aspartate transcarbamylase, and dihydroorotase) protein (Ito and Uchino 1973; Iwahana et al. 1996). The purified human protein is active in several different oligomerization states as is its Syrian hamster homologue. The most abundant form of the latter is a hexamer, and the active human protein is annotated as a hexamer by inference (Ito and Uchino 1973; Lee et al. 1985).
