ENZYME entry: EC 1.4.3.4

Accepted Name
Monoamine oxidase.
Alternative Name(s)
Adrenaline oxidase.
Amine oxidase.
Amine oxidase (flavin-containing).
Tyraminase.
Tyramine oxidase.
Reaction catalysed
RCH(2)NHR' + H(2)O + O(2) <=> RCHO + R'NH(2) + H(2)O(2)
Cofactor(s)
FAD.
Comment(s)
  • Catalyzes the oxidative deamination of neurotransmitters and biogenic amines.
  • Acts on primary amines, and also on some secondary and tertiary amines.
  • It differs from EC 1.4.3.21, as it can oxidize secondary and tertiary amines but not methylamine.
  • Inhibited by acetylenic compounds such as chlorgyline, 1-deprenyl and pargyline but, unlike EC 1.4.3.21 and EC 1.4.3.22, it is not inhibited by semicarbazide.
  • Formerly EC 1.4.3.9.
