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         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}.
CC   -!- SEQUENCE CAUTION:
