目的:研究ATP和S140对Ⅰ型和Ⅱ型核糖体失活蛋白(RIP)失活核糖体的影响.方法:采用凝胶电泳分析特征RIP作用片断(R片断),以及改进的二步法标记苯丙氨酸外源poly(U)翻译体系,定量检测外加因子对RIP失活核糖体作用的影响.结果:ATP和S140对所有用于检测的Ⅰ型和Ⅱ型RIP失活核糖体的功能均表现出不同程度的促进作用.对于Ⅰ型RIP中克木毒蛋白、天花粉毒蛋白、γ苦瓜子毒蛋白、丝瓜毒蛋白A、丝瓜毒蛋白S和Ⅱ型RIP中蓖麻毒蛋白、蓖麻毒蛋白A链;辛纳毒蛋白、辛纳毒蛋白A链,IC50增强活性比率分别为3108,15,151,45,51和47,7,26,12.结论:首次发现ATP和S140对Ⅱ型RIP及其A链具有活性增强作用.克木毒蛋白和辛纳毒蛋白在对ATP和S140的辅助需求方面有显著区别
