Protein

D-phenylhydantoinase

Gene

hyuA

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Catalyzes the stereospecific hydrolysis of the cyclic amide bond of D-hydantoin derivatives with an aromatic side chains at the 5'-position. Has no activity on dihydropyrimidines. The physiological function is unknown.1 Publication

Cofactori

Zn2+Curated1 Publication, Ni2+Curated1 Publication, Co2+Curated1 Publication, Mn2+Curated1 PublicationNote: Binds 2 divalent metal cations per subunit. Can use zinc, nickel, cobalt or manganese.Curated1 Publication

Kineticsi

Hydantoin derivatives with an aliphatic or no side chain at their 5'-position results in a much lower level of activity than those with aromatic side chains at the 5'-position.

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.
