Inducible gene expression systems represent powerful tools for studying essential gene function and for validation of drug targets in bacteria. Even if several regulated promoters have been characterized, only a few of them have been successfully used in Mycobacteria. Here we describe a successful mycobacterial gene regulation system based on the presence of two chromosomally encoded repressors: Pip and TetR, and a tunable promoter (Pptr) that allows a tight regulation of gene expression.

Abstract
Inducible gene expression systems represent powerful tools for studying essential gene function and for validation of drug targets in bacteria. Even if several regulated promoters have been characterized, only a few of them have been successfully used in Mycobacteria. Here we describe a successful mycobacterial gene regulation system based on the presence of two chromosomally encoded repressors: Pip and TetR, and a tunable promoter (Pptr) that allows a tight regulation of gene expression.File in questo prodotto:
