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.
Pathway	Nitrogen metabolism; (S)-allantoin degradation; allantoate from (S)-allantoin: step 1/1. HAMAP-Rule MF_01645
Subunit structure	Homotetramer By similarity.
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.
