Antipain kills Escherichia coli K-12 cells in an exponential manner beginning 1 h after its addition. Mutant strains, delta cya and crp, which are unable to synthesize cyclic adenosine 3',5'-monophosphate (cAMP) and the cAMP receptor protein, respectively, are not affected. Addition of cAMP (5 mM) to antipain-treated mutant strains causes killing of delta cya cells, but not crp cells. Thus the lethal effect of antipain is dependent upon cAMP and its receptor protein.
抗痛素在添加后1小时开始以指数方式杀死大肠杆菌K-12细胞。分别无法合成环腺苷3',5'-单磷酸(cAMP)和cAMP受体蛋白的突变菌株delta cya和crp不受影响。向经抗痛素处理的突变菌株中添加cAMP(5 mM)会导致delta cya细胞死亡,但不会导致crp细胞死亡。因此,抗痛素的致死作用取决于cAMP及其受体蛋白。
