assayed as substrates for the diamine oxidases from pea seedlings and pig kidney. KM and Vmax data are reported, mainly for the pea enzyme. N-Alkylputrescines and C-alkylcadaverines are generally poorer substrates than the parent compounds with up to 4500-fold reduction in Vmax. There is significantly less variation in KM values, indicating that the binding site of the pea enzyme is relatively non-specific
合成了一系列腐胺和尸胺衍生物,并作为豌豆幼苗和猪肾中二胺氧化酶的底物进行了分析。报告了K M和V max数据,主要是豌豆酶。N-烷基腐胺和C-烷基尸胺通常是比母体化合物差的底物,其V max降低多达4500倍。K M值的变化明显较少,表明豌豆酶的结合位点是相对非特异性的,并且酶的特异性位于催化阶段。这表明不良的底物可能是便利的,短命的二胺氧化酶抑制剂。
