Two Escherichia coli tRNA gene clusters, tRNA1Tyr (su3+ and su3-) and tRNA2Tyr, tRNA2Gly (su+36), tRNA3Thr, were transcribed in a purified in vitro system. Evidence indicates that the adjacent tRNA genes are transcribed together as a common precursor of large size, which, on incubation with crude cell extracts, yields mature tRNA molecules.
两个大肠杆菌tRNA基因簇,即tRNA1Tyr(su3+和su3-)以及tRNA2Tyr、tRNA2Gly(su+36)、tRNA3Thr,在一个纯化的体外系统中进行转录。证据表明,相邻的tRNA基因作为一个大尺寸的共同前体一起转录,该前体与粗细胞提取物一起温育时,会产生成熟的tRNA分子。
