IUBMB Comments
The enzyme catalyses the conversion of assorted 3-oxo-Delta4 steroids into their corresponding 5alpha form. Substrates for the mammalian enzyme include testosterone, progesterone, and corticosterone. Substrates for the plant enzyme are brassinosteroids such as campest-4-en-3-one and (22alpha)-hydroxy-campest-4-en-3-one. cf. EC 1.3.99.5, 3-oxo-5alpha-steroid 4-dehydrogenase (acceptor).
