Function

[AAUA_ALCFA] Oxidizes primary aromatic amines and, more slowly, some long-chain aliphatic amines, but not methylamine or ethylamine. Uses azurin as an electron acceptor to transfer electrons from the reduced tryptophylquinone cofactor.^{[1] [2] [3] [4] [5] [6] [7]} [AAUB_ALCFA] Oxidizes primary aromatic amines and, more slowly, some long-chain aliphatic amines, but not methylamine or ethylamine.
