CC   -!- FUNCTION: Catalyzes the conversion of allantoin (5-
CC       ureidohydantoin) to allantoic acid by hydrolytic cleavage of the
CC       five-member hydantoin ring. {ECO:0000255|HAMAP-Rule:MF_01645}.
CC   -!- CATALYTIC ACTIVITY: (S)-allantoin + H(2)O = allantoate.
CC       {ECO:0000255|HAMAP-Rule:MF_01645}.
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01645};
CC       Note=Binds 2 Zn(2+) ions per subunit. {ECO:0000255|HAMAP-
CC       Rule:MF_01645};
CC   -!- PATHWAY: Nitrogen metabolism; (S)-allantoin degradation;
CC       allantoate from (S)-allantoin: step 1/1. {ECO:0000255|HAMAP-
CC       Rule:MF_01645}.
CC   -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_01645}.
CC   -!- PTM: Carbamylation allows a single lysine to coordinate two zinc
CC       ions. {ECO:0000255|HAMAP-Rule:MF_01645}.
CC   -!- SIMILARITY: Belongs to the metallo-dependent hydrolases
CC       superfamily. Allantoinase family. {ECO:0000255|HAMAP-
CC       Rule:MF_01645}.
