Two copies of the structural gene for the elongation factor EF-Tu have been identified in Escherichia coli: one near rif and the other near str. The latter seems to belong to a single transcriptional unit together with the genes for ribosomal protein S7, S12 (str) and the elongation factor EF-G (fus).
在大肠杆菌中已鉴定出延伸因子EF-Tu结构基因的两个拷贝:一个靠近利福平基因(rif),另一个靠近链霉素基因(str)。后者似乎与核糖体蛋白S7、S12(str)以及延伸因子EF-G(fus)的基因属于同一个转录单位。
