Protegrin-1 Kill Switch
Usage and Biology
A Protogrin-1 (Anti-microbial peptide), pBad (arabinose sensitive promoter) controlled e. coli kill switch.
Protegrin-1 coding region under the influence of a pBad-strong promotor. Protegrin-1 is an '18-residue beta-sheet peptide isolated from porcine leukocytes with antimicrobial activity against a broad range of microorganisms.' (Steinberg et al 1997) It has its effect by pore membrane disruption (Lam et al 2006) and possibly also by effects such as activation of membrane-damaging proteases (Bierbaum 1985) and has anti-microbial activity against E Coli (Aumelas 2004).
The presence of the pBad promoter allows the expression of Protegrin-1 to be controlled by differing concentrations of arbinose.
