Abstract
E. coli genes for tRNAasp and tRNAtrp are transcribed by eukaryotic RNA polymerase III upon injection into nuclei of Xenopus oocytes. This indicates that some bacterial tRNA genes contain RNA polymerase III promoter sequences. We discuss evolutionary aspects of this finding.
摘要
将大肠杆菌天冬氨酸tRNA和色氨酸tRNA的基因注射到非洲爪蟾卵母细胞核中后，它们会由真核生物RNA聚合酶III进行转录。这表明一些细菌tRNA基因含有RNA聚合酶III启动子序列。我们讨论了这一发现的进化方面。
