TorA Signal Peptide - Silver Fusion Compatible

Design Notes

This part was designed for Silver-fusion compatibility. It is in plasmid pSB3K3.

Another TorA BioBrick was constructed by the 2008 Wisconsin iGEM team. This part, however, is not fusion-compatible. Accordingly, our team decided to design a Silver-fusion compatible part. Additionally, the sequence that we chose to use is different than that used by the Wisconsin team. Based on a number of references (Palmer, 2004; NCBI, Institute for Biomolecular Design), we selected a 126 bp sequence.

Analysis of the existing Wisonsin-designed TorA sequence by a simple BLAST search on NCBI yields no matches. The 2009 IBB Pune iGEM team is deriving a fusion-compatible TorA sequence from the part originally designed by Wisconsin 2008 (see BBa_K233307). For this purpose, they selected to not use the Silver-fusion method. Accordingly, the addition of our Silver-fusion TorA BioBrick part adds an alternative for studying protein secretion.

Source

This part was designed to have the Silver-fusion prefix and suffix, and was synthetically produced by DNA 2.0. The obtained plasmid was then cut with EcoRI and SpeI. The insert was then ligated with a BioBrick compatible vector, pSB3K3. This part has been sequenced.
