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 the reaction: (S)-dihydroorotate + acceptor = orotate + 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. Catalysis of the reaction: (S)-dihydroorotate + O2 = orotate + H2O2.
