项目摘要
To investigate the function of eicosapentaenoic acid (EPA) in the bacterial cell membrane, Escherichia coli lacking either tolC, acrA, or acrB gene was transformed with the EPA biosynthesis pfa genes. The susceptibility of these recombinants possessing EPA against antibiotics was compared with that of their reference cells without EPA. Recombinants with EPA were more resistant to antibiotics than their references without EPA. Electrophoresis of the hydrophobic protein fraction of the recombinants indicated that more AcrA protein was accumulated in the cells with EPA than in those without EPA, suggesting that EPA might be involved in the exclusion of antibiotics by the TolC-AcrAB system in the bacterial cell membranes.
为了研究二十碳五烯酸(EPA)在细菌细胞膜中的功能,用EPA生物合成pfa基因转化缺乏tolC、acrA或acrB基因的大肠杆菌。将这些含有EPA的重组子对抗生素的敏感性与不含EPA的参考细胞的敏感性进行比较。添加EPA的澄清剂对抗生素的耐药性高于不添加EPA的对照品。重组子的疏水蛋白电泳结果表明,在含有EPA的细胞中积累了更多的AcrA蛋白,这表明EPA可能参与了细菌细胞膜上TolC-AcrAB系统对抗生素的排斥作用。
