BBa_K215002 Is a BioBrick part that was made to work in conjunction with the Secretion System (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.

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.

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 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.

  • This Part is composed of:
    • [http://partsregistry.org/wiki/index.php/Part:BBa_K215201 BBa_K215201]: Display Vector with 5 trans-membrane OMPA
    • [http://partsregistry.org/wiki/index.php/Part:BBa_K215250 BBa_K215250]: Coding Sequence for fusion protein scaffold, 1 trans-membrane OMPA
    • [http://partsregistry.org/wiki/index.php/Part:BBa_K215251 BBa_K215251]: Coding Sequence for fusion protein scaffold, 5 trans-membrane OMPA
