PURL: https://purl.expasy.org/enzyme/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
a secondary aliphatic amine + O2 + H2O = a primary amine + an aldehyde + H2O2
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.
