1 The inactivation of pea-seedling diamine oxidase by peroxidase and 1,5-diaminopentane. Cadaverine amine oxidase copper containing 1 Homo sapiens
2 The rate of oxidative deamination of 1,5-diaminopentane by pea-seedling extracts, which contain diamine oxidase [diamine-oxygen oxidoreductase (deaminating), EC 1.4.3.6], was increased by adding pyridoxal or pyridoxal phosphate. Cadaverine amine oxidase copper containing 1 Homo sapiens
3 This inactivation only occurred when 1,5-diaminopentane was the substrate and depended on a second thermolabile factor in the extract besides the diamine oxidase. Cadaverine amine oxidase copper containing 1 Homo sapiens
4 Purified diamine oxidase, when catalysing the oxidation of 1,5-diaminopentane, was rapidly inactivated in the presence of peroxidase. Cadaverine amine oxidase copper containing 1 Homo sapiens
5 It is suggested that peroxidase catalyses the further oxidation of the product of the oxidative deamination of 1,5-diaminopentane to a compound that inactivates diamine oxidase. Cadaverine amine oxidase copper containing 1 Homo sapiens
