The University of California at San Francisco 2006 iGEM Team

The international Genetically Engineered Machine Competition is an opportunity for emerging young scientists of all disciplines to tinker with the proverbial Rube Goldberg machine of life. This is the UCSF team's third year in the program, and to celebrate our three years, we had a members-only contest to develop a team logo. More information on the logo is forthcoming.

95% of the logo submissions managed to make 'Death Wish V' allusions

Aspirations, Dreams...

CheW, a most powerful protein

The UCSF iGEM team, aka Team Death Wish V, has endeavored to control chemotaxis by selectively expressing CheW mutants which will participate in an orthogonal interaction with the methyl-accepting chemotaxis protein Tar. The project will be broken down into three major components:

• Design and construction of the orthogonal interaction: An existing orthogonal interaction, to be used as a starting point prior to computational redesign, was discovered by [http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=pubmed&cmd=Retrieve&dopt=AbstractPlus&list_uids=1860813&query_hl=2&itool=pubmed_docsum Liu and Parkinson] in 1991.

Our success and livelihood as a team hinges on these two residues

• Implementation of the genetic switch: This will allow us to toggle between the selective expression of either Chew.
• Validation of chemotactic properties through specially developed assay: originally developed by the good folks at the [http://www.physics.upenn.edu/facultyinfo/goulian.html Goulian Lab] in 2006.

The obvious choice

Receptor Specificity

Much work is available in the literature regarding the changing of chemoreceptor specificity. Some of the options include:

• Directed evolution
• Computational redesign
• Chimeric construction (perisplasmic and cytoplasmic domains of the different receptors can be swapped)
