Catalyzes the oxidative deamination of a wide range of aliphatic monoamines and diamines (PubMed:27315927). The physiological electron acceptor is an azurin-like blue protein (PubMed:27315927). A + an aliphatic amine + H2O = AH2 + an aldehyde + NH4(+) Contains 1 cysteine tryptophylquinone per subunit. Inhibited by various carbonyl reagents, such as p-nitrophenylhydrazine (pNPH), 2,4-dinitrophenylhydrazine, semicarbazide and hydroxylamine. Optimum pH is around 8.0 for n-butylamine oxidation. Heterotrimer of an alpha, a beta and a gamma subunit. Is probably co-translocated into the periplasm when associated with the alpha and/or beta subunit, which contain both a signal peptide. The cysteine tryptophylquinone (CTQ) is generated by oxidation of the indole ring of a tryptophan residue to form tryptophylquinone, followed by covalent cross-linking with a cysteine residue. With methionine sulfoxide. Belongs to the quinohemoprotein amine dehydrogenase subunit gamma family. The oxidation form of Met-30 is subject of controversy and could be the artifactual result of sample handling.
