Acting on paired donors, with incorporation or reduction of molecular oxygen;
With reduced iron-sulfur protein as one donor, and incorporation of one atom of oxygen into the other donor
progesterone,reduced-ferredoxin:oxygen oxidoreductase (15beta-hydroxylating)
progesterone + 2 reduced [2Fe-2S] ferredoxin + O2 = 15beta-hydroxyprogesterone + 2 oxidized [2Fe-2S] ferredoxin + H2O [RN:
oxidized [2Fe-2S] ferredoxin [CPD:
The enzyme from the bacterium Bacillus megaterium hydroxylates a variety of 3-oxo-Delta4-steroids in position 15beta. Ring A-reduced, aromatic, and 3beta-hydroxy-Delta4-steroids do not serve as substrates .
