有效的微生物代谢工程依赖于高效的基因转移。在这里,我们提出了一个简单的筛选策略,可以部署到隔离罕见的,高转化的变异。该程序用于将溶剂产生生物体巴氏梭菌的转化频率增加三至四个数量级。分离能够高效DNA转移的巴氏梭菌突变体的方法。将DNA转移效率提高三到四个数量级。巴氏梭菌染色体蛋白的结构维持参与DNA转移。
Effective microbial metabolic engineering is reliant on efficient gene transfer. Here we present a simple screening strategy that may be deployed to isolate rare, hypertransformable variants. The procedure was used to increase the frequency of transformation of the solvent producing organism Clostridium pasteurianum by three to four orders of magnitude. A procedure to isolate C. pasteurianum mutants capable of high efficient DNA transfer. Increase DNA transfer efficiency by three to four orders of magnitude. Structural maintenance of chromosome proteins of C. pasteurianum are involved in DNA transfer.
