Suppression of streptomycin dependence in Escherichia coli strain K-114, a spectinomycin-sensitive strain, is correlated with modification of 30S ribosomal protein P4, the component modified in spectinomycin-resistant mutants. The mutant is unusual in that reversion from dependence has previously been correlated only with modification in 30S protein P4a. Introduction into K-114 of another mutation conferring spectinomycin resistance results in a further alteration in protein P4.
在对壮观霉素敏感的大肠杆菌K - 114菌株中,链霉素依赖性的抑制与30S核糖体蛋白P4的修饰相关,该蛋白是在壮观霉素抗性突变体中发生修饰的成分。该突变体不同寻常之处在于,此前从依赖性回复仅与30S蛋白P4a的修饰相关。将另一个赋予壮观霉素抗性的突变引入K - 114会导致蛋白P4进一步改变。
