progesterone,reduced-ferredoxin:oxygen oxidoreductase (15beta-hydroxylating)

progesterone + 2 reduced [2Fe-2S] ferredoxin + O2 = 15beta-hydroxyprogesterone + 2 oxidized [2Fe-2S] ferredoxin + H2O [RN:R09587]

R09587
Reaction

progesterone [CPD:C00410];
reduced [2Fe-2S] ferredoxin [CPD:C22150];
O2 [CPD:C00007]

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 [2].
