Function
function
Catalyzes the reversible cyclization of carbamoyl aspartate to dihydroorotate.
Catalytic activity
- (S)-dihydroorotate + H2O = N-carbamoyl-L-aspartate + H+
Cofactor
Note: Binds 2 Zn2+ ions per subunit.
Pathway
Pyrimidine metabolism; UMP biosynthesis via de novo pathway; (S)-dihydroorotate from bicarbonate: step 3/3.
