Abstract
The Butyrivibrio fibrisolvens tet(W) gene is located on the conjugative transposon TnB1230. TnB1230 encodes transfer proteins with 48 to 67% identity to some of those encoded by Tn1549. tet(W) is flanked by directly repeated sequences with significant homology to oxygen-insensitive nitroreductases. The 340 nucleotides upstream of tet(W) are strongly conserved and are required for tetracycline resistance.
摘要
溶纤维丁酸弧菌tet(W)基因位于接合转座子TnB1230上。TnB1230编码的转移蛋白与Tn1549编码的某些转移蛋白具有48%至67%的同一性。tet(W)两侧是与氧不敏感硝基还原酶具有显著同源性的直接重复序列。tet(W)上游的340个核苷酸高度保守，是四环素抗性所必需的。
