EOG81K1V1 GO:0051537 2/5 2 iron, 2 sulfur cluster binding molecular_function "Interacting selectively and non-covalently with a 2 iron, 2 sulfur (2Fe-2S) cluster; this cluster consists of two iron atoms, with two inorganic sulfur atoms found between the irons and acting as bridging ligands." [GOC:ai, PMID:15952888, Wikipedia:Iron-sulfur_cluster] EOG81K1V1 GO:0046872 2/5 metal ion binding molecular_function "Interacting selectively and non-covalently with any metal ion." [GOC:ai] EOG81K1V1 GO:0016491 2/5 oxidoreductase activity molecular_function "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." [GOC:go_curators]
