General annotation (Comments)

Function

Catalyzes the conversion of allantoin (5-ureidohydantoin) to allantoic acid by hydrolytic cleavage of the five-member hydantoin ring By similarity. HAMAP-Rule MF_01645

Catalytic activity

(S)-allantoin + H2O = allantoate. HAMAP-Rule MF_01645

Cofactor

Binds 2 zinc ions per subunit By similarity. HAMAP-Rule MF_01645

Pathway

Nitrogen metabolism; (S)-allantoin degradation; allantoate from (S)-allantoin: step 1/1. HAMAP-Rule MF_01645

Subunit structure

Homotetramer By similarity. HAMAP-Rule MF_01645

Post-translational modification

Carbamylation allows a single lysine to coordinate two zinc ions By similarity. HAMAP-Rule MF_01645

Sequence similarities

Belongs to the DHOase family. Allantoinase subfamily.
