Abstract In the oxidation of a homologous series of monodansyldiamines by pea seedling diamine oxidase, monodansylcadaverine was the best substrate. Monodansyldiaminohexane was oxidized at 74% of the rate with monodansylcadaverine, and monodansylputrescine and monodansyldiaminopropane were oxidized only very slowly. The optimum pH for the oxidation of monodansylcadaverine was 8.5, and the Km 2.4 ×
摘要 在豌豆幼苗二胺氧化酶氧化一系列同源单丹酰二胺中,单丹酰尸胺是最好的底物。单丹酰二氨基己烷以单丹酰尸胺的 74% 的速率被氧化,单丹酰腐胺和单丹酰二氨基丙烷仅被非常缓慢地氧化。单丹酰尸胺氧化的最佳 pH 值为 8.5,Km 为 2.4 × 10−4 M。在最佳条件下,腐胺的氧化速度是单丹酰尸胺的 11 倍。单丹酰尸胺被二胺氧化酶氧化,以及等量赖氨酸的彻底丹酰化最终在形成的丹酰 5-氨基戊醛中显示出相同的荧光,表明在两个反应中都化学计量地转化为该产物。
