Quorum Sensing in B.substilis

The idea is to fuse our split protease on the components of the quorum sensing system of B.substilis. The signal peptide is the product of ComX gene. The sensor is the transmembrane receptor ComP which autophosphorylates(the first half of the split protease will be attached on ComP). ComA is the relay compoment which gets phosphorylated by ComP (the second part of the split protease will be attached on the ComA). When ComP and Coma associate that would produce the active protease.
