Function
function
Catalyzes the conversion of allantoin (5-ureidohydantoin) to allantoic acid by hydrolytic cleavage of the five-member hydantoin ring.
Catalyzes the reversible cyclization of carbamoyl aspartate to dihydroorotate.
Catalytic activity
- (S)-allantoin + H2O = allantoate + H+
Cofactor
Note: Binds 2 Zn2+ ions per subunit.
Pathway
Nitrogen metabolism; (S)-allantoin degradation; allantoate from (S)-allantoin: step 1/1.
