The pelB leader sequence is a sequence of amino acids which when attached to a protein, directs the protein to the periplasmic membrane of E. coli, where the sequence is removed by pelB peptidase. It is used to direct coat protein-antigen fusions to the cell surface.

Designed de novo by Chou et al. (2008)
GW-Q5 is a cationic alpha-helical peptide designed de novo using the natural peptide Magainin as a template, upon which variants that maintained major structural determinants like electric charge, hydrophobicity and angular momentum were designed. This peptide showed antimicrobial activity against Gram-positive and Gram-negative bacteria, and in particular it showed a Minimab Inhibitory Concentration 4 ??g/ml against Vibrio harveyi, 8 ??g/ml against V. parahemoliticu,s and 8??g/ml against Escherichia coli3.

It's complicated

Chou et al. synthesized GW-Q5 by solid-phase peptide synthesis, and thus they provide an Aminoacid sequence but no DNA sequence. Therefore we had to design a DNA sequence that had the codons corresponding to the given Peptide.

PelBQ5 was obtained from biopart BBa_J32015.
GW-Q5 was obtained de novo by Chou et al. (2008)

The present construction will allow the secretion of an antimicrobial peptide into de medium by the 5??? joining of the PelB leader sequence to the antimicrobial peptide GW-Q5.
PelB is a 20 aminoacid N??? terminal sequence which directs the proteins for their exportation into the medium trough type II secretion, in which the protein goes to the periplasm before exportation via the Sec translocation machinery in the outer membrane

PelB and GwQ5 were fused by PCR making a Reverse primer which added to the 3' extreme of PelB the first 20 base pairs of GW-Q5.
