Ras guanyl-nucleotide exchange factor activity

Stimulates the hydrolysis and exchange of guanyl nucleotides by the GTPase Ras.

oxidoreductase activity, acting on NADH or NADPH

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

The aggregation and bonding together of a set of components to form a protein complex.

Rho guanyl-nucleotide exchange factor activity

Stimulates the exchange of guanyl nucleotides by the GTPase Rho.

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.

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.
