- anhydrotetracycline + NADPH + H+ + O2 12-dehydrotetracycline + NADP+ + H2O
The 4 substrates of this enzyme are anhydrotetracycline, NADPH, H+, and O2, whereas its 3 products are 12-dehydrotetracycline, NADP+, and H2O.
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 one atom o oxygen into the other donor. The systematic name of this enzyme class is anhydrotetracycline,NADPH:oxygen oxidoreductase (6-hydroxylating). Other names in common use include ATC oxygenase, and anhydrotetracycline oxygenase. This enzyme participates in tetracycline biosynthesis and biosynthesis of type ii polyketide products.
