CC -!- FUNCTION: Catalyzes the conversion of allantoin (5-ureidohydantoin) to
CC allantoic acid by hydrolytic cleavage of the five-member hydantoin
CC ring. {ECO:0000255|HAMAP-Rule:MF_01645}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(S)-allantoin + H2O = allantoate + H(+); Xref=Rhea:RHEA:17029,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:15678,
CC ChEBI:CHEBI:17536; EC=3.5.2.5; Evidence={ECO:0000255|HAMAP-
CC 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; allantoate
CC from (S)-allantoin: step 1/1. {ECO:0000255|HAMAP-Rule:MF_01645}.
CC -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_01645}.
CC -!- PTM: Carboxylation allows a single lysine to coordinate two zinc ions.
CC {ECO:0000255|HAMAP-Rule:MF_01645}.
CC -!- SIMILARITY: Belongs to the metallo-dependent hydrolases superfamily.
CC Allantoinase family. {ECO:0000255|HAMAP-Rule:MF_01645}.
