Design Notes

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.

The S•Tag sequence is a novel fusion peptide tag for recombinant proteins that allows detection by a rapid, sensitive homogeneous assay or by colorimetric detection in Western blots. Proteins can also be rapidly purified from crude extracts using a one step affinity separation method. The system is based on the strong interaction between the 15aa S•Tag and 103aa S-protein, both of which are derived from RNase A, resulting in reconstituted ribonucleolytic activity


It is a fusion protein so biobrick prefixes and suffixes have been modified to 10 and 24 bp, removing the bp between the flanking restriction sites and the sequence. Otherwise it would read out of frame with 8bp overlap.

The signal sequence PelB and S*Tag sequence came from Novagen. The C-terminus of Neisseria gonorrhoeae IgA Protease NCBI accession number AE004969
