Abstract

The 3-isopropylmalate dehydrogenase gene from an extreme thermophile, Thermus thermophilus, was not expressed in Escherichia coli unless a palindromic structure around the ribosome binding site was eliminated or a leader open reading frame was introduced into the upstream flanking region of the gene. This report suggests a way to increase the expression of this gene, with a high G+C content, in E. coli.

摘要

来自嗜热栖热菌(Thermus thermophilus)这种极端嗜热菌的3-异丙基苹果酸脱氢酶基因,在大肠杆菌中无法表达,除非核糖体结合位点周围的回文结构被消除,或者在该基因的上游侧翼区域引入一个前导开放阅读框。本报告提出了一种在大肠杆菌中提高这个高G+C含量基因表达的方法。
