Description
LL-37 antimicrobial peptide with human codon usage under the Arabinose promoter with GFP generator. 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 cationic antimicrobial peptides, such as LL-37. This composite part allows MarA expression in presence of IPTG, by using the LacI promoter and the RBS based on Elowitz repressilator.
Notes
LL-37 has the codon usage for humans. Using E. coli codon usage may inhibit protein function by wrong folding.
