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

BioBricks

Target Vector

Target structure.png

[http://partsregistry.org/wiki/index.php/Part:BBa_K215002 BBa_K215002] Is a BioBrick part that was made to work in conjunction with the Secretion System ([http://partsregistry.org/wiki/index.php/Part:BBa_K215107 BBa_K215107]). When used it creates a fusion protein, that contains the prtB secretion signal recognized by the secretion system. It also fuses to the protein a nano-tag that is able to bind Streptavidin, TEV protease site (for isolating your protein from the fusion) and Histidine Epitote Tags for easy protein purification.

  • This part is composed of:
    • [http://partsregistry.org/wiki/index.php/Part:BBa_K215000 BBa_K215000]: Protein Expression Vector
    • [http://partsregistry.org/wiki/index.php/Part:BBa_K215001 BBa_K215001]: Fusion protein sequence
  • This part is used in:
    • [http://partsregistry.org/wiki/index.php/Part:BBa_K215010 BBa_K215010]: GFP fusion protein
    • [http://partsregistry.org/wiki/index.php/Part:BBa_K215011 BBa_K215011]: [http://partsregistry.org/wiki/index.php/Part:BBa_K215090 BBa_K215090] (organic phosphotriesterase) fusion protein

Secretion System

[http://partsregistry.org/wiki/index.php/Part:BBa_K215107 BBa_K215107] Is a BioBrick version of the Type 1 secretion system of Erwinia Chrysanthemi. It secretes 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



Display structure.png

[http://partsregistry.org/wiki/index.php/Part:BBa_K215200 BBa_K215200] is a Display vector that will allow for the presentation of any protein onto the surface of a cell by fusing the protein to 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.
