In enzymology a precorrin-3B synthase (EC 1.14.13.83) is an enzyme that catalyzes the chemical reactionprecorrin-3A + NADH + H+ + O2 precorrin-3B + NAD+ + H2OThe 4 substrates of this enzyme are precorrin 3A NADH H+ and O2 whereas its 3 products are precorrin 3B NAD+ 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.
