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