Biological function
The B.subtilis bacteriophage phi3T encode the Aim system to make lysis-lysogeny decision. The AimR is a transcription factor, the AimP is the propeptide of the mature signal peptide. However, binding of AimP to the 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.
The AimR-AimP system and its role in the phage lysis-lysogeny decision, cited from reference [1].
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.
