The MarA protein acts as a transcriptional activator in E. coli, it allows the expression of the acrAB and tolC operons, which activate the AcrAB-TolC efflux pump, a mechanism that has been related with resistance to organic solvents, dyes, detergents, antibiotics such as chloramphenicol, tetracycline, novobiocin, erythromycin, fusidic acid and cloxacillin, as well as to cationic antimicrobial peptides, such as LL-37, HNP-2 and HBD-1.

For high-efficiency synthetic processs, we tried two methods. 1, 1-deoxy-D-xylulose 5-phosphate（DXP）synthase, Dxs, is down-regulated when its downstream material has been produced to some extent. So, we tried to over-express, another DXP synthase, nDXP, that rarely has been used in normal conditions. 2, Using genomic editing method, we tried to knock out synthase, that we used to produce unnecessary by product.

The MarA protein acts as a transcriptional activator in E. coli, it allows the expression of the acrAB and tolC operons, which activate the AcrAB-TolC efflux pump, a mechanism that has been related with resistance to organic solvents, dyes, detergents, antibiotics such as chloramphenicol, tetracycline, novobiocin, erythromycin, fusidic acid and cloxacillin, as well as to cationic antimicrobial peptides, such as LL-37, HNP-2 and HBD-1.

We used device BBa_K1230004 to characterise this part.
