Identifier Name Description
GO:0016491 oxidoreductase activity 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.
GO:0003824 catalytic activity Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
GO:0016627 oxidoreductase activity, acting on the CH-CH group of donors 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.
GO:0003865 3-oxo-5-alpha-steroid 4-dehydrogenase activity Catalysis of the reaction: a 3-oxo-5-alpha-steroid + acceptor = a 3-oxo-delta(4)-steroid + reduced acceptor.
GO:0003674 molecular_function Elemental activities, such as catalysis or binding, describing the actions of a gene product at the molecular level. A given gene product may exhibit one or more molecular functions.
GO:0016229 steroid dehydrogenase activity Catalysis of an oxidation-reduction (redox) reaction in which one substrate is a sterol derivative.
GO:0033765 steroid dehydrogenase activity, acting on the CH-CH group of donors 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.
