(3Z)-4-(2-carboxyphenyl)-2-oxobut-3-enoic acid

The two substrates of this enzyme are 1-hydroxy-2-naphthoic acid and oxygen. Its product is (3Z)-4-(2-carboxyphenyl)-2-oxobut-3-enoic acid.[1][2]

This enzyme participates in phenanthrene metabolism. It employs one cofactor, iron.

Nomenclature

This enzyme belongs to the family of oxidoreductases, specifically those acting on single donors with O2 as oxidant and incorporation of two atoms of oxygen into the substrate (oxygenases). The oxygen incorporated need not be derived from O2. The systematic name of this enzyme class is 1-hydroxy-2-naphthoate:oxygen 1,2-oxidoreductase (decyclizing). Other names in common use include 1-hydroxy-2-naphthoate dioxygenase, 1-hydroxy-2-naphthoate-degrading enzyme, and 1-hydroxy-2-naphthoic acid dioxygenase.[1]
