许多多蛋白复合物的结构和功能研究依赖于重组蛋白的过表达。表达实验的快速修改和复合物的多样化通常对这些项目的成功至关重要;因此,自动化越来越不可或缺。我们介绍Acembl,一个通用的和自动化的系统,在大肠杆菌中的蛋白质复合物的表达,使用重组工程,以促进多基因组装和多样化。我们使用Acembl证明了蛋白质复合物的表达,包括完整的原核holotranslocon的生产。
Structural and functional studies of many multiprotein complexes depend on recombinant-protein overexpression. Rapid revision of expression experiments and diversification of the complexes are often crucial for success of these projects; therefore, automation is increasingly indispensable. We introduce Acembl, a versatile and automatable system for protein-complex expression in Escherichia coli that uses recombineering to facilitate multigene assembly and diversification. We demonstrated protein-complex expression using Acembl, including production of the complete prokaryotic holotranslocon.
