University of Washington 2009 iGEM Team Accomplishments

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 int he Registry). Find this in our wiki

Synthesized and BioBricked type I secretion system from Erwinia Chrysanthemi

• Find these in our wiki
• [http://partsregistry.org/wiki/index.php/Part:BBa_K215107 BBa_K215107], Type I secretion system from Erwinia Chrysanthemi, constitutive expression, low copy, STRONG PROMOTER
• [http://partsregistry.org/wiki/index.php/Part:BBa_K215107 BBa_K215107], Type I secretion system from Erwinia Chrysanthemi, constitutive expression, low copy, MEDIUM PROMOTER
• [http://partsregistry.org/wiki/index.php/Part:BBa_K215107 BBa_K215107], Type I secretion system from Erwinia Chrysanthemi: constitutive expression, low copy, WEAK PROMOTER

Developed assay to quantify protein secretion

• This assay assess for the presence of secreted His-tagged protein in the growth media by running media over a nickel column (His-tagged proteins will be retained), wash column, and elute protein. Eluted protein is quantified by comparing to a calculated standard curve. Find this in our wiki

Designed new modular surface display system

• This BioBrick is designed to express any protein as a cell surface display protein, using the well-characterized Lpp-OmpA cell surface display system. Generated BioBrick, functionality not confirmed. Find this in our wiki

Computationally design novel Biotin-binding protein using Rosetta

• Find this on our wiki

Gain real-world synthetic biology experience

• We learned about the power of synthetic biology to address real-world problems, gained experience in designing and constructing our own molecular biology projects, and discovered that proficiency in troubleshooting is a must with synthetic biology. Find us in our wiki

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 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.

• 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

• This Part is used in:
  • [http://partsregistry.org/wiki/index.php/Part:BBa_K215210 BBa_K215210]: Display system (1 trans-membrane) in protein expression vector
  • [http://partsregistry.org/wiki/index.php/Part:BBa_K215211 BBa_K215211]: Display system (5 trans-membrane) in protein expression vector
  • [http://partsregistry.org/wiki/index.php/Part:BBa_K215260 BBa_K215260]: [http://partsregistry.org/wiki/index.php/Part:BBa_K215210 BBa_K215210] fused to Streptavidin
  • [http://partsregistry.org/wiki/index.php/Part:BBa_K215261 BBa_K215261]: [http://partsregistry.org/wiki/index.php/Part:BBa_K215211 BBa_K215211] fused to Streptavidin

• Current Status: In progress
