== Function ==
[https://www.uniprot.org/uniprot/AAUA_ALCFA 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.<ref>PMID:11495996</ref> <ref>PMID:16279953</ref> <ref>PMID:8188594</ref> <ref>PMID:7876189</ref> <ref>PMID:17087503</ref> <ref>PMID:17005560</ref> <ref>PMID:16614214</ref>

== Publication Abstract from PubMed ==
We present an atomic-level description of the reaction chemistry of an enzyme-catalyzed reaction dominated by proton tunneling. By solving structures of reaction intermediates at near-atomic resolution, we have identified the reaction pathway for tryptamine oxidation by aromatic amine dehydrogenase. Combining experiment and computer simulation, we show proton transfer occurs predominantly to oxygen O2 of Asp(128)beta in a reaction dominated by tunneling over approximately 0.6 angstroms. The role of long-range coupled motions in promoting tunneling is controversial. We show that, in this enzyme system, tunneling is promoted by a short-range motion modulating proton-acceptor distance and no long-range coupled motion is required.
