Catalysis of the two-electron reduction of the disulfide of thioredoxins with electrons from ferredoxin involving a 4Fe-4S cluster and an adjacent active-site disulfide. Catalysis of an oxidation-reduction (redox) reaction in which an iron-sulfur protein acts as a hydrogen or electron donor and reduces dinitrogen. Catalysis of an oxidation-reduction (redox) reaction in which an iron-sulfur protein acts as a hydrogen or electron donor and reduces NAD or NADP. 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. 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 hydrogen acts as an electron donor and reduces an iron-sulfur protein. Catalysis of the reaction: pheophorbide a + reduced ferredoxin + 2 O2 = red chlorophyll catabolite (RCC) + oxidized ferredoxin + H2O. 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.
