Some TTA containing antibiotic resistant genes and regulatory genes still expressed in bldA deficient mutants, suggesting that there is an alternative pathway to translate UUA codon while bldA tRNA is not available. bldA突变菌株中含TTA密码子的抗生素抗性基因、抗生素调节基因仍有表达,暗示存在一个替代bldAtRNA翻译UUA密码子的机制。
In this study we tried to localize bad~ mutation, clone bad~+ gene, and reveal the alternative mechanism through which UUA is translated instead of bldA tRNA when it is absent. 本研究试图定位bad~-突变,克隆bad~+基因,揭示替代bldAtRNA翻译UUA密码子的途径。
