Oxidative deamination of aliphatic amines by rat aorta semicarbazide-sensitive amine oxidase

Peter H. Yu

Open publisher page 76 citations

Abstract

Rat aorta semicarbazide-sensitive amine oxidase (SSAO) exhibits very high affinity in the deamination of an homologous series of aliphatic amines of 1 to 18 straight chain carbon atoms. The Km value decreases substantially as the chain length of these amines increases. The Vmax values are higher for the short chain amines. Diamines are poor substrates for SSAO or are not acted upon by the enzyme. The substrate preference for SSAO differs from that for monoamine oxidase.
