Abstract
A chromosomal DNA fragment from the erythromycin-sensitive bacterium Corynebacterium glutamicum ATCC 13032 was shown to mediate resistance against erythromycin, tetracycline, puromycin, and bleomycin in Escherichia coli. Multicopy cloning of the fragment did not cause a resistance phenotype in C. glutamicum. The corresponding gene encodes a hydrophobic protein with 12 potential transmembrane-spanning ex-helical segments showing similarity to drug-H+ antiporters.
摘要
来自对红霉素敏感的谷氨酸棒状杆菌ATCC 13032的一个染色体DNA片段被证明可介导大肠杆菌对红霉素、四环素、嘌呤霉素和博来霉素产生抗性。该片段的多拷贝克隆在谷氨酸棒状杆菌中未产生抗性表型。相应的基因编码一种具有12个潜在跨膜α螺旋片段的疏水蛋白，该蛋白与药物-H⁺反向转运体具有相似性。
