Catalysis of an oxidation-reduction (redox) reaction in which a nitrogenous group, excluding NH and NH2 groups, acts as a hydrogen or electron donor and reduces an iron-sulfur protein.
Catalysis of an oxidation-reduction (redox) reaction in which an iron-sulfur protein acts as a hydrogen or electron donor and reduces a hydrogen or electron acceptor.
An aerobic respiration process in which a sulfur-containing molecule (hydrogen sulfide, sulfur, sulfite, thiosulfate, and various polythionates) is oxidized.
OBSOLETE. Catalysis of an oxidation-reduction (redox) reaction in which hydrogen is the electron donor and reduces an acceptor other than a cytochrome, an iron-sulfur protein, NAD, NADP or a quinone or similar compound.
