Abstract
Transcription of the bacteriophage lambda nutL region from the PL promoter on a multicopy plasmid in Escherichia coli causes a reduction in growth rate and in transcription of rRNA relative both to total transcription and to transcription of tRNAs that are not encoded in rRNA operons. These observations support the hypothesis, previously based on nut site DNA sequence homology, that the phage lambda and rRNA antitermination systems are related.
摘要
在大肠杆菌中，多拷贝质粒上噬菌体λ nutL区域从PL启动子开始转录，相对于总转录以及相对于非rRNA操纵子编码的tRNA转录而言，会导致生长速率降低以及rRNA转录减少。这些观察结果支持了此前基于nut位点DNA序列同源性得出的假说，即噬菌体λ和rRNA抗终止系统是相关的。
