Design Notes
This is the G178C mutant of the small RNA SgrS(wt).
Teppei Morita et.al’ s work suggest that two mutations (C85G and C87G) in ptsG mRNA could completely impair the ability of SgrS to downregulate its expression, while compensatory mutations of SgrS (G178C and G176C) restore the gene silencing ability. Therefore, such a site mutation is designed for biological orthogonality.
Also, since a specific repression effect is favored in our comparator device, the characteristics of the conjugate mutated ptsG/SgrS system meet the need quite well.
