In enzymology, 3-oxosteroid 1-dehydrogenase (EC 1.3.99.4) is an enzyme that catalyzes the chemical reaction
In the example shown, the enzyme converts androstenedione to boldione using an unknown electron acceptor. It can also convert other steroids with a keto group in the equivalent 3-position as androstenedione into 3-oxo-Delta1-steroids.[1][2]
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donor with other acceptors. The systematic name of this enzyme class is 3-oxosteroid:acceptor Delta1-oxidoreductase. Other names in common use include 3-oxosteroid Delta1-dehydrogenase, Delta1-dehydrogenase, 3-ketosteroid-1-en-dehydrogenase, 3-ketosteroid-Delta1-dehydrogenase, 1-ene-dehydrogenase, 3-oxosteroid:(2,6-dichlorphenolindophenol) Delta1-oxidoreductase, 4-en-3-oxosteroid:(acceptor)-1-en-oxido-reductase, Delta1-steroid reductase, and 3-oxosteroid:(acceptor) Delta1-oxidoreductase.
