CC -!- FUNCTION: Catalyzes the conversion of urocanate to 4-imidazolone-5-
CC propionate. {ECO:0000255|HAMAP-Rule:MF_00577}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=4-imidazolone-5-propanoate = H2O + trans-urocanate;
CC Xref=Rhea:RHEA:13101, ChEBI:CHEBI:15377, ChEBI:CHEBI:17771,
CC ChEBI:CHEBI:77893; EC=4.2.1.49; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_00577};
CC -!- COFACTOR:
CC Name=NAD(+); Xref=ChEBI:CHEBI:57540;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00577};
CC Note=Binds 1 NAD(+) per subunit. {ECO:0000255|HAMAP-Rule:MF_00577};
CC -!- PATHWAY: Amino-acid degradation; L-histidine degradation into L-
CC glutamate; N-formimidoyl-L-glutamate from L-histidine: step 2/3.
CC {ECO:0000255|HAMAP-Rule:MF_00577}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00577}.
