Biological Function

The B.subtilis bacteriophage phi3T employs the AimR-AimP QS system to make the lysis-lysogeny decision. AimP is the pre-pro-peptide. It is 48aa long. The mature signal peptide of AimP is SAIRGA. Binding of the mature signal peptide to AimR will disrupt the dimer forms of AimR. After that, the AimR can no longer bind to the promoter of AimX, a potential non coding RNA involved in the process of lysis-lysogeny.

Design

By combining the expression of AimR and AimP components, we want to develop a synthetic QS system in B. subtilis for target gene autoinhibition. A synthetic communication pathway between B. subtilis strains by co-culturing AimP-producing “sender” cells with AimR-sensing “receiver” cells to inhibit gene expression was also designed.
