oxidoreductase activity, acting on NADH or NADPH, NAD or NADP as acceptor

Catalysis of an oxidation-reduction (redox) reaction in which NADH or NADPH acts as a hydrogen or electron donor and reduces NAD+ or NADP.

oxidoreductase activity, acting on NADH or NADPH, disulfide as acceptor

oxidoreductase activity, acting on NADH or NADPH, disulphide as acceptor

Catalysis of an oxidation-reduction (redox) reaction in which NADH or NADPH acts as a hydrogen or electron donor and reduces a disulfide group.

The covalent or conformational alteration of one or more amino acid residues within a protein, resulting in a change in the properties of that protein.

The chemical reactions involving a toxin, a poisonous compound (typically a protein) that is produced by cells or organisms and that can cause disease when introduced into the body or tissues of an organism.

oxidoreductase activity, acting on NADH or NADPH, quinone or similar compound as acceptor

Catalysis of an oxidation-reduction (redox) reaction in which NADH or NADPH acts as a hydrogen or electron donor and reduces a quinone or a similar acceptor molecule.

The specific processes that generate the ability of an organism to cause disease in another.

Catalysis of the reaction: NADH + H+ + 2 monodehydroascorbate = NAD+ + 2 ascorbate.

oxidoreductase activity, acting on NADH or NADPH, nitrogenous group as acceptor

Catalysis of an oxidation-reduction (redox) reaction in which NADH or NADPH acts as a hydrogen or electron donor and reduces a nitrogenous group.

The process of introducing a phosphoric group on to a protein.

Catalysis of the reaction: peptidyl-L-lysyl-peptide + H2O + O2 = peptidyl-allysyl-peptide + NH3 + H2O2.

Enables the directed movement of choline into, out of, within or between cells. Choline (2-hydroxyethyltrimethylammonium) is an amino alcohol that occurs widely in living organisms as a constituent of certain types of phospholipids and in the neurotransmitter acetylcholine.

Interacting selectively and simultaneously with one or more signal transduction molecules, usually acting as a scaffold to bring these molecules into close proximity either using their own SH2/SH3 domains (e.g.Grb2) or those of their target molecules (e.g. SAM68).
