摘要
背景:蛋白质的可逆磷酸化调节真核细胞中的许多关键功能。磷酸化由蛋白激酶催化,大部分磷酸化发生在丝氨酸和苏氨酸残基的侧链上。由蛋白激酶产生的磷酸单酯被蛋白磷酸酶水解。在没有磷酸酶的情况下,磷酸烷基二甲酯在25℃下水解的半衰期超过1万亿年; knon~2 x 10-20 sec-1。因此,ser / thr磷酸酶对可逆磷酸化控制的过程至关重要。 方法:本评价基于现有数据库中搜索的文献。我们比较了PPP家族磷酸酶(PPPase)的催化机制和靶向这些酶的抑制剂的相互作用。 结果:PPPase是金属依赖性水解酶,其将水解速率([kcat / kM] / knon)提高~1021倍,使其成为地球上最强大的已知催化剂。生化和结构研究表明,通过10个保守氨基酸,DXH(X)~26DXXDR(X)〜20-26NH(X)~50H(X)~25-45R(X)~30,实现了PPP酶的显着催化效率。 -40H。六个作为金属配位残基。四个位置并定向基质磷酸盐。两个金属离子和10个催化残基一起定位磷酰基和活化的桥接水/氢氧化物亲核试剂,用于对基质磷原子的内联攻击。 PPPase在物种之间是保守的,并且许多结构上不同的天然毒素共同进化以靶向这些酶 结论:尽管催化位点是保守的,但是存在开发这种重要的金属酶组的选择性抑制剂的机会。
