Function
function
Catalyzes the condensation of carbamoyl phosphate and aspartate to form carbamoyl aspartate and inorganic phosphate, the committed step in the de novo pyrimidine nucleotide biosynthesis pathway.
Catalytic activity
- carbamoyl phosphate + L-aspartate = H+ + N-carbamoyl-L-aspartate + phosphate
Pathway
Pyrimidine metabolism; UMP biosynthesis via de novo pathway; (S)-dihydroorotate from bicarbonate: step 2/3.
