  • FUNCTION Catalyzes the conversion of allantoin (5-ureidohydantoin) to allantoate by hydrolytic cleavage of the five-member hydantoin ring. Catalyzes the first step of the ureide allantoin degradation followed by the sequential activity of AAH, UGLYAH and UAH which allows a complete purine breakdown without the intermediate generation of urea (By similarity).CATALYTIC ACTIVITY (S)-allantoin + H2O = allantoate + H(+)COFACTOR Binds 2 Zn(2+) ions per subunit.PATHWAY Nitrogen metabolism; (S)-allantoin degradation; allantoate from (S)-allantoin: step 1/1.SUBUNIT Homotetramer.PTM Carboxylation allows a single lysine to coordinate two zinc ions.SIMILARITY Belongs to the metallo-dependent hydrolases superfamily. Allantoinase family.
