Isolation and analysis of strong and regulatable promoters of mycobacteria should be useful tools to aid the expression of cloned genes in mycobacteria. In the present study, we have mapped the transcriptional start site of the inducible acetamidase gene of Mycobacterium smegmatis and studied the mechanism of its regulation. Northern blot, reverse transcription-PCR and primer extension analysis studies were used to determine the position of the promoter.
分离和分析分枝杆菌的强启动子和可调控启动子,对于在分枝杆菌中表达克隆基因应是有用的工具。在本研究中,我们已定位耻垢分枝杆菌诱导型乙酰胺酶基因的转录起始位点,并研究了其调控机制。采用Northern印迹法、逆转录-聚合酶链反应和引物延伸分析研究来确定启动子的位置。
