What is "aminoimidazolase"

In enzymology, an aminoimidazolase is an enzyme that catalyzes the chemical reaction

4-aminoimidazole + HO $\rightleftharpoons$ unidentified product + NH

Thus, the two substrates of this enzyme are 4-aminoimidazole and HO, whereas its two products are unidentified product and NH.

This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in cyclic amidines. The systematic name of this enzyme class is 4-aminoimidazole aminohydrolase. This enzyme is also called 4-aminoimidazole hydrolase. This enzyme participates in purine metabolism. It employs one cofactor, iron.
