WebJul 28, 2015 · Basically, the prototypical QS system of Gram-negative bacteria consists of a so-called LuxI-type synthase that produces the acyl-HSL and a cognate LuxR-type receptor that senses the signal. Once the signal exceeds a specific threshold concentration the LuxR-like receptor binds to DNA and activates or deactivates the expression of several genes ... WebIn addition, Salmonella is able to perform a type of cell-to-cell communication called quorum sensing, which leads to differential gene expression. The quorum sensing system mediated by AI-1, acyl homoserine lactones (AHLs), is incomplete in Salmonella because the luxI homolog gene, which encodes for AI-1 synthase, is missing in the genome…
