pBSChag
A plasmid backbone we developed that is intended for use with the hag promoter. It integrates into the flgM site of the B. subtilis genome. flgM binds the SigD transcription factor and inactivates it, thus blocking the P hag promoter, one of the strongest promoters discovered.
Introduction
The Bacillus BioBrick Box designed by LMU-Munich iGEM 2012 was used extensively in the McGill 2022 project. The box contains three B. subtilis integrative vectors targeted to the amyE, thrC, and lacA sites, as well as constitutive and inducible promoters with varying strengths. We decided to design a fourth integrative vector and an accompanying promoter as our parts contribution.
Biology
pBSChag is a modification of pBS1C of the BioBrick Box to integrate into the flgM site. Like pBS1C, pBSChag will have an ampicillin selection marker for E. coli and chloramphenicol for B. subtilis. The “hag” in the vector name indicates that it is designed to be used with Phag as the promoter, but others also work fine. The flgM gene is an inhibitor of Phag; pBSChag eliminates this inhibition by integrating and disrupting flgM.
