EOG82NMJQ GO:0003960 1/2 NADPH:quinone reductase activity molecular_function "Catalysis of the reaction: NADPH + H+ + quinone = NADP+ + semiquinone." [EC:1.6.5.5] EOG82NMJQ GO:0008270 1/2 zinc ion binding molecular_function "Interacting selectively and non-covalently with zinc (Zn) ions." [GOC:ai] EOG82NMJQ GO:0016491 1/2 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] EOG82NMJQ GO:0004252 1/2 serine-type endopeptidase activity molecular_function "Catalysis of the hydrolysis of internal, alpha-peptide bonds in a polypeptide chain by a catalytic mechanism that involves a catalytic triad consisting of a serine nucleophile that is activated by a proton relay involving an acidic residue (e.g. aspartate or glutamate) and a basic residue (usually histidine)."
