PlcR-PapR - Gram+ve Quorum Peptide
The PlcR-PapR fusion peptide has been derived from the Bacillus cereus quorum signalling system. This group of Gram-positive bacteria employs the PlcR quorum system to initiate virulence factors under appropriate cell density conditions. Synthesized as a propeptide, this fusion molecule is exported from the cell via the secA pathway, cleaved by an extracellular protease and re-imported into the cell via an oligopeptide permease. Both the extracellular protease as well as olidopeptide permease are ubiquitous structures to the Gram-positive cell wall. A such, any gram-positive bacteria expressing the PlcR-PapR protein should be able to both process as well as import the activating form of the fusion peptide.

Improvement:TMMU-China 2017
Author:Yizhen Xu Summary:In this improvement, we splited this part into two parts that can be used in cell-cell communication.
From reference [1], the PlcR-PapR fusion peptide can activate gene expression without the PapR signal peptide. Because alteration of the export signal, this fusion peptide can not be exported and re-imported into the cell to activate the PlcR transcription factor. In our improvement, we provided two new parts. One is the PlcR protein (BBa_K2279002), the other is PapR signal peptide (BBa_K2279003). Combining these two new parts, we can build autoinduction system and Sender-Receiver Cells to enable cell-cell communication.
