Catalyzes the oxidative deamination of a wide range of primary aliphatic and aromatic amines (PubMed:10346915). The physiological electron acceptor is the constitutive cytochrome c550 (PubMed:11168384). an aliphatic amine + 2 Fe(III)-[cytochrome c550] + H2O = an aldehyde + 2 Fe(II)-[cytochrome c550] + 2 H(+) + NH4(+) Contains 1 cysteine tryptophylquinone per subunit. Inhibited by carbonyl reagents such as hydrazine, hydroxylamine, phenylhydrazine and semicarbazide. 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. Induced by growth on methylamine, n-butylamine or benzylamine. 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. Belongs to the quinohemoprotein amine dehydrogenase subunit gamma family. Extended N-terminus.
