Gifsy2 promoters and Gifsy2 repressor gtgR

Gifsy2 is a temperate phage present in many of the Salmonella enterica serovar Typhimurium strains. This part contains the Gifsy2 promoters and the Gifsy2 repressor. The promoters are divergent; consisting of pR[Gifsy2] and pRM[Gifsy2]. Downstream of the pRM[Gifsy2] promoter is the repressor gtgR. gtgR binds to the operator regions located between the two divergent promoters and is predicted to act both as an activator of the pRM[Gifsy2] and a repressor of the pR[Gifsy2]. The regulatory system is similar to the one found in lambda phages but induction is repressor cleavage independent. Instead small lexA regulated anti-repressor proteins bind to the repressor and prevents its DNA activity. The part has been used and tested in E. Coli.
