The deamination of n-pentylamine by monoamine oxidase and a semicarbazide-sensitive amine oxidase of rat heart

Abstract

n-Pentylamine is deaminated by homogenates of rat heart. Clorgyline inhibition curves at 10 and 100 microM n-pentylamine indicated that this substrate was deaminated by MAO-A, -B and a clorgyline-resistant amine oxidase sensitive to inhibition by semicarbazide. These results have been compared with two other commonly used monoamine substrates, beta-phenethylamine and benzylamine.
