Abstract

In this chapter, we present a bidirectional promoter library toolbox to evaluate fast and efficiently the optimal conditions for the balanced co-expression of two target genes. As a proof-of-concept, we demonstrate the co-expression of CYP505x and the GroEL/ES complex, which resulted in noticeably elevated enzyme activity with one of the de-novo-designed promoters of the library. The new toolbox offers a straightforward one-pot cloning approach and is highly modular. As such, the method presented here should be of great interest to any gene co-expression study.
