Demonstrated that at least one new BioBrick Part of our own design works as expected
- [http://partsregistry.org/wiki/index.php?title=Part:BBa_K215000 BBa_K215000] Target Expression Vector - expresses a favorite protein fused to streptavidin-binding Nano-Tag, secretion tag that directs export of the protein, and a His tag - all tags are removable by incubation with TEV protease. Find this in our wiki
- [http://partsregistry.org/wiki/index.php?title=Part:BBa_K215091 BBa_K215091] Expresses OpdA, a nerve agent-degrading enzyme. Find this in our wiki
- [http://partsregistry.org/wiki/index.php?title=Part:BBa_K215000 BBa_K215000] Protein Expression Vector - when IPTG-induced, expresses a protein with strong promoter and RBS (a good combination of BioBricks not previously found in the Registry). Find this in our wiki

BioBricks
Target Vector
|
|
[http://partsregistry.org/wiki/index.php/Part:BBa_K215002 BBa_K215002] Is a BioBrick part that was designed to work in conjunction with the Secretion System ([http://partsregistry.org/wiki/index.php/Part:BBa_K215107 BBa_K215107]). Expression of protein from this vector creates a fusion protein that contains the prtB secretion signal recognized by the secretion system. The fusion protein also contains: a Nano-Tag to the protein that is able to bind Streptavidin, Histidine Epitope Tags for easy protein purification, and TEV protease sites for removing all tags from the expressed protein.
|
Secretion System
|
|
[http://partsregistry.org/wiki/index.php/Part:BBa_K215107 BBa_K215107] Is the BioBrick version of the Type 1 secretion system from Erwinia Chrysanthemi. It directs the secretion of proteins that contain the prtB C-terminus Epitote tag. To create a fusion protein with the prtB tag see [http://partsregistry.org/wiki/index.php/Part:BBa_K215002 BBa_K215002].
|
Display System
|
|
[http://partsregistry.org/wiki/index.php/Part:BBa_K215200 BBa_K215200] is a Display vector that will allow for the presentation of any protein on the cell surface by fusing the protein to the transmembrane region of Outer Membrane Protein A (OmpA). The fusion protein contains a GS peptide linker to space the displayed protein away from the outer membrane and also contains a TEV protease site to allow for purification of the displayed protein.
