CC -!- FUNCTION: Catalyzes the hydrolytic cleavage of the carbon-nitrogen bond
CC in imidazolone-5-propanoate to yield N-formimidoyl-L-glutamate. It is
CC the third step in the universal histidine degradation pathway.
CC {ECO:0000255|HAMAP-Rule:MF_00372}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=4-imidazolone-5-propanoate + H2O = N-formimidoyl-L-glutamate;
CC Xref=Rhea:RHEA:23660, ChEBI:CHEBI:15377, ChEBI:CHEBI:58928,
CC ChEBI:CHEBI:77893; EC=3.5.2.7; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_00372};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00372};
CC Name=Fe(3+); Xref=ChEBI:CHEBI:29034;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00372};
CC Note=Binds 1 zinc or iron ion per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_00372};
CC -!- PATHWAY: Amino-acid degradation; L-histidine degradation into L-
CC glutamate; N-formimidoyl-L-glutamate from L-histidine: step 3/3.
CC {ECO:0000255|HAMAP-Rule:MF_00372}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00372}.
CC -!- SIMILARITY: Belongs to the metallo-dependent hydrolases superfamily.
CC HutI family. {ECO:0000255|HAMAP-Rule:MF_00372}.
