Protein

Allantoinase

Gene

allB

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

Functioni

Catalyzes the conversion of allantoin (5-ureidohydantoin) to allantoic acid by hydrolytic cleavage of the five-member hydantoin ring.2 Publications

Catalytic activityi

(S)-allantoin + H2O = allantoate.1 Publication

Cofactori

Zn2+2 PublicationsCurated, Ni2+2 PublicationsCurated, Co2+2 PublicationsCurated, Mn2+2 PublicationsCuratedNote: Binds 2 Zn(2+) ions per subunit. Can also use Ni(2+), Co(2+) or Mn(2+).2 PublicationsCurated

Enzyme regulationi

Severely inhibited by copper, and competitively inhibited by dithiothreitol (DTT). Zinc concentrations above 2.5 mM and cobalt or nickel concentrations above 1 mM are inhibitors.2 Publications
