目的:构建麦芽糖诱导表达系统,提高外源蛋白的产量。枯草芽孢杆菌随后,为了改善PmalA衍生系统的性能,通过逐渐缩短PmalA启动子的长度并改变预测的MalR结合位点与-35区域之间的间隔来进行诱变。此外,麦芽糖利用基因(malL和yvdK)的缺失提高了PmalA启动子活性。最后,利用该麦芽糖诱导表达系统,与PhpaII系统相比,荧光素酶和D-氨基酰化酶的产量均得到了提高。可用于外源蛋白的高效表达。
Objectives:To improve heterologous proteins production, we constructed a maltose-inducible expression system in Bacillus subtilis.Results:An expression system based on the promoter for maltose utilization constructed in B. subtilis. Successively, to improve the performance of the PmalA-derived system, mutagenesis was employed by gradually shortening the length of PmalApromoter and altering the spacing between the predicted MalR binding site and the -35 region. Furthermore, deletion of the maltose utilization genes (malL and yvdK) improved the PmalApromoter activity. Finally, using this efficient maltose-inducible expression system, we enhanced the production of luciferase and D-aminoacylase, compared with the PhpaIIsystem.Conclusions:A maltose-inducible expression system was constructed and evaluated. It could be used for high level expression of heterologous proteins production.
