Tightly regulated gene expression system in Salmonella enterica serovar Typhimurium

J Bacteriol. 2002 Nov;184(21):6056-9. doi: 10.1128/JB.184.21.6056-6059.2002.

Abstract

A new Salmonella enterica serovar Typhimurium strain has been constructed to facilitate tightly regulated gene expression. Arabinose-inducible and glucose-repressible expression of a T7 RNA polymerase gene that has been integrated with an adjacent araC-P(BAD) control element into the bacterial chromosome allows dynamic control of T7 promoter-driven RNA transcription.
