luxI_codon optimized S.cerevisiae

LuxI is an acyl homoserine lactone synthase, most known from the bacterium Aliivibrio fischeri. LuxI is a basic component of the quorum sensing system of A. fischeri. Bacteria use it as a communication module to regulate expression of genes in a cell density-dependent manner. This part contains a variant of the synthase codon optimized for the common yeast, Saccharomyces cerevisiae. Besides the codon optimization, the construct contains also type IIS restriction sites (BsaI), useful for example for the Golden Gate assembly cloning method. Since yeast is a eukaryotic organism and the quorum sensing system is encountered in prokaryotes, a codon optimized variant for utilization in an eukaryotic organism represents the beginning of designing quorum sensing-based control systems in eukaryotes. For example, LuxI is coupled with the design of a synthetic promoter, which is supposed to be activated by binding of the quorum sensing molecule together with the regulator (LuxR) to the promoter to induce expression of a reporter gene or a lysis gene to control cell population.

Usage and Biology

This part can be used as a component for designing synthetic circuits in S.cerevisiae. For instance, in our project, we used this gene to induce expression of a reporter after activation of a synthetic, self designed promoter.
