[Abstract]  Corynebacterium glutamicum is a versatile workhorse for industrial bioproduction of many kinds of chemicals and fuels, notably amino acids. Development of advanced genetic engineering tools is urgently demanded for systems metabolic engineering of C. glutamicum. Recently unveiled clustered regularly interspaced short palindromic repeats (CRISPR) and their CRISPR-associated proteins (Cas) are now revolutionizing genome editing. The CRISPR/Cas9 system from Streptococcus pyogenes that utilizes NGG as protospacer adjacent motif (PAM) and has good targeting specificity can be developed into a powerful tool for efficient and precise genome editing of C. glutamicum. In this protocol, we described the general procedure for CRISPR/Cas9-mediated ssDNA ... [摘要]  谷氨酸棒杆菌是多种化学品和燃料,特别是氨基酸的工业生物生产的多功能工具。 迫切需要开发先进的基因工程工具用于 C的系统代谢工程。谷氨酸。 最近推出的聚集的有规律的间隔短回文重复序列(CRISPR)和它们的CRISPR相关蛋白(Cas)现在正在彻底改变基因组编辑。 来自 Streptococcus pyogenes 的CRISPR / Cas9系统利用NGG作为原型间隔区相邻基序(PAM)并具有良好的靶向特异性,可以开发成为 C的高效和精确基因组编辑的有力工具。谷氨酸。 在该方案中,我们描述了 C中CRISPR / Cas9介导的ssDNA重组工程的一般程序。谷氨酸。 可以在 C中引入小的修改。 谷氨酸染色体,编辑效率高达90%。
【背景】革兰氏阳性土壤细菌 Corynebacterium glutamicum 是用于氨基酸,生物燃料和聚合物构建模块的工业生物生产的多功能工具(Becker et al。,2016)。在 C工程的早期阶段。谷氨酸,随机诱变结合对氨基酸类似物的表型抗性的阳性选择是最常用的策略(Vertes et al。,2005)。 C中的遗传操作。谷氨酸(glutamicum)于1984年启动,并成为菌株改良的关键促成策略(Ozaki et al。,1984)。常规使用的基因破坏和插入 ...
