Escherichia coli cells with plasmids bearing the valS gene were constructed from the Clark-Carbon collection. Their increased valyl-tRNA synthetase (EC 6.1.1.9) activity was not matched by commensurate production of a modifying peptide during T4 infection. Thus, phage vs gene expression is set to modify the normal amount of valyl-tRNA synthetase activity.
携带valS基因的质粒的大肠杆菌细胞是从克拉克-卡本收集物构建而来的。在T4感染期间,它们增加的缬氨酰-tRNA合成酶(EC 6.1.1.9)活性与修饰肽的相应产量不匹配。因此,噬菌体vs基因表达被设定为改变缬氨酰-tRNA合成酶活性的正常量。
