In enzymology, a benzene 1,2-dioxygenase (EC 1.14.12.3) is an enzyme that catalyzes the chemical reaction
Contents
The 4 substrates of this enzyme are benzene, NADH, H+, and O2, whereas its two products are cis-cyclohexa-3,5-diene-1,2-diol and NAD+.
Classification
This enzyme belongs to the family of oxidoreductases, specifically those acting on paired donors, with O2 as oxidant and incorporation or reduction of oxygen. The oxygen incorporated need not be derived from O2 with NADH or NADPH as one donor, and incorporation of two atoms o oxygen into the other donor.
Nomenclature
The systematic name of this enzyme class is benzene,NADH:oxygen oxidoreductase (1,2-hydroxylating). Other names in common use include benzene hydroxylase, and benzene dioxygenase.
Biological role
This enzyme participates in naphthalene and anthracene degradation. It has 4 cofactors: FAD, Iron, Sulfur, and Iron-sulfur.
