3-(hydroxyamino)phenol Mutase

In enzymology, a 3-(hydroxyamino)phenol mutase (EC 5.4.4.3) is an enzyme that catalyzes the chemical reaction

3-hydroxyaminophenol aminohydroquinone

Hence, this enzyme has one substrate, 3-hydroxyaminophenol, and one product, aminohydroquinone.

This enzyme belongs to the family of isomerases, specifically those intramolecular transferases transferring hydroxy groups. The systematic name of this enzyme class is 3-(hydroxyamino)phenol hydroxymutase. Other names in common use include 3-hydroxylaminophenol mutase, and 3HAP mutase.
