The two-component system of S. mutans senses the CSP to regulate the expression of ClyR
CSP is a quorum sensing signaling molecule of S. mutans, and its concentration is positively correlated with the amount of S. mutans. ComD is a membrane-bound histidine kinase (HK) capable of autophosphorylation in response to sensing CSP. The response regulatory factor (RR) ComE then catalyzes the transfer of phosphorylated groups to aspartic residues in its receptor region. Phosphorylated ComE (P-ComE) is allosterically transformed into an active conformation that binds upstream to the CSP-sensitive promoter nlmC and activates transcription. Then expressing ClyR, a chimeric lysin, is composed of a catalytic domain from PlyC and a cell-wall binding domain from PlySs2. ClyR can recognize and lyse the cell wall of S. mutans and avoids the biofilm formed by S. mutans on the surface of our bacteria.
