Catalyzes the conversion of allantoin (5-ureidohydantoin) to allantoic acid by hydrolytic cleavage of the five-member hydantoin ring.UniRule annotation

Catalytic activityi

(S)-allantoin + H2O = allantoate.UniRule annotation

Cofactori

Zn2+UniRule annotationNote: Binds 2 Zn2+ ions per subunit.UniRule annotation

Pathwayi: (S)-allantoin degradation

This protein is involved in step 1 of the subpathway that synthesizes allantoate from (S)-allantoin.UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Allantoinase (allB)
This subpathway is part of the pathway (S)-allantoin degradation, which is itself part of Nitrogen metabolism.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
