Catalysis of the reaction: a 3-oxo-5-alpha-steroid + acceptor = a 3-oxo-delta(4)-steroid + reduced acceptor. Catalysis of an oxidation-reduction (redox) reaction in which a CH-CH group acts as a hydrogen or electron donor and reduces a hydrogen or electron acceptor, and in which one substrate is a sterol derivative. Catalysis of the reaction: a 3-oxosteroid + acceptor = a 3-oxo-D1-steroid + reduced acceptor. Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced. Catalysis of an oxidation-reduction (redox) reaction in which one substrate is a sterol derivative. Catalysis of the reaction: a 3-oxo-5-beta-steroid + acceptor = a 3-oxo-D4-steroid + reduced acceptor. Catalysis of an oxidation-reduction (redox) reaction in which a CH-CH group acts as a hydrogen or electron donor and reduces a hydrogen or electron acceptor.
