Design Notes
The sequence recognised by the SecA pathway had to be included in the synthesised sequence so as to ensure that the fusion peptide is adequately exported fro the cell. A ribozyme binding site (RBS) was also included in the final sequence. Furthermore, the sequence was codon optimized for Lactobacillus gasseri.
Source
This sequence was adapted from the naturally-occurring fusion peptide found in the Bacillus cereus genome.
