Because S49 cells are senstivie to killing by cyclic AMP (cAMP), mutants can be selected which have a variety of defects in their ability to generate or respond to cAMP. One class of mutants, that with deficiencies in cAMP-dependent protein kinase, has been extensively characterized genetically and biochemically.
由于S49细胞对环磷酸腺苷(cAMP)杀伤敏感,因此可以筛选出在产生或响应cAMP能力方面存在各种缺陷的突变体。一类突变体,即cAMP依赖性蛋白激酶存在缺陷的突变体,已经在遗传学和生物化学方面得到了广泛的表征。
