一般描述

2-碘乙酰胺是一种巯基-烷基化试剂,常用于生物化学、细胞培养和蛋白质组学研究中的肽图分析。作用方式与碘乙酸类似,主要通过共价结合蛋白质半胱氨酸残基上的巯基,防止二硫键形成。它在多种应用中发挥重要作用,比如在蛋白质二维电泳中,可作为去泛素化酶(DUB)抑制剂和肽酶抑制剂,减少拖尾并提高分辨率。也常用于肽质谱法从头测序中的样品制备。

它会与蛋白质中的半胱氨酸和组氨酸残基发生特定的相互作用,影响各种酶(如,核糖核酸酶)。与组氨酸缓慢反应的抑制特性令其适合蛋白酶研究(如,半胱氨酸蛋白酶)。碘乙酰胺的优势在于不可逆地抑制酶,形成稳定的蛋白衍生物,是蛋白质结构、蛋白行为和酶抑制研究的有用工具。

应用

碘乙酰胺已用于:
  • 防止蛋白质样品发生酶促二硫键还原反应
  • 在细胞生物学研究中抑制甘油醛-3-磷酸脱氢酶,有效阻断ATP生产

生化/生理作用

碘乙酰胺在肽测序中胱氨酸残基的烷基化试剂。它是活性位点上含有胱氨酸的酶的的一种不可逆抑制剂。它与组氨酸残基的反应速度要慢得多,但这种活性是核糖核酸酶抑制的原因。
