Aspartate transcarbamoylase domain of human CAD bound to PALA

Released:

Function and Biology Details

Reactions catalysed:
Carbamoyl phosphate + L-aspartate = phosphate + N-carbamoyl-L-aspartate
L-glutamine + H(2)O = L-glutamate + NH(3)
(S)-dihydroorotate + H(2)O = N-carbamoyl-L-aspartate
(1a) ATP + HCO(3)(-) = ADP + carboxyphosphate
(1a) L-glutamine + H(2)O = L-glutamate + NH(3)
