Function
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
- 4-imidazolone-5-propanoate + H2O = N-formimidoyl-L-glutamate
Cofactor
Fe3+ (UniProtKB | Rhea| CHEBI:29034 )
Note: Binds 1 zinc or iron ion per subunit.
Pathway
Amino-acid degradation; L-histidine degradation into L-glutamate; N-formimidoyl-L-glutamate from L-histidine: step 3/3.
