Enzyme Commission Summary:
A mitochondrial outer-membrane flavoprotein (FAD) that catalyses the oxidative deamination of neurotransmitters and biogenic amines [Edmondson04]. Acts on primary amines, and also on some secondary and tertiary amines. It differs from EC 184.108.40.206, primary-amine oxidase as it can oxidize secondary and tertiary amines but not methylamine. This enzyme is inhibited by acetylenic compounds such as chlorgyline, 1-deprenyl and pargyline but, unlike EC 220.127.116.11 and EC 18.104.22.168 (diamine oxidase), it is not inhibited by semicarbazide.
