Catalysis of an oxidation-reduction (redox) reaction in which a sulfur-containing group acts as a hydrogen or electron donor and reduces a hydrogen or electron acceptor. Catalysis of the reaction: hydrogen sulfide + a quinone = S0 + a hydroquinone. Catalysis of the reaction: 2 thiosulfate + 2 6-decylubiquinone = tetrathionate + 2 6-decylubiquinol. 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 a sulfur-containing group acts as a hydrogen or electron donor and reduces quinone or a related compound. Catalysis of the reaction: 2 glutathione + dehydroascorbate = glutathione disulfide + ascorbate.
