We have constructed transcriptional fusion vectors for use in Bacteroides spp., a genus of gram-negative obligate anaerobes found in high numbers in the human colon. The reporter group in these vectors is a promoterless beta-glucuronidase gene from Escherichia coli (uidA). Two of the vectors (pMJF-2 and pMJF-3) replicate in Bacteroides spp. The third, pCQW-1, does not replicate in Bacteroides spp. and can be used to introduce E. coli beta-glucuroindase fusions into the Bacteroides chromosome.
我们构建了用于拟杆菌属的转录融合载体,拟杆菌属是革兰氏阴性专性厌氧菌,在人类结肠中大量存在。这些载体中的报告基团是来自大肠杆菌的无启动子β-葡萄糖醛酸酶基因(uidA)。其中两个载体(pMJF-2和pMJF-3)可在拟杆菌属中复制。第三个载体pCQW-1不能在拟杆菌属中复制,可用于将大肠杆菌β-葡萄糖醛酸酶融合基因导入拟杆菌属染色体。
