iGEM Davidson – Missouri Western 2010:
Foundational Advances in Biology and the Knapsack Problem

The Davidson/Missouri Western multidisciplinary team is using synthetic biology to address a mathematical problem in Escherichia coli. Specifically, we are addressing the Knapsack Problem, an NP-complete problem that asks, “Given a finite number of weighted items, can one find a subset of these items that completely fills a knapsack of fixed capacity?”

In our design, weighted items are represented by versions of TetA genes that confer measurably distinct levels of tetracycline resistance. We have altered the codons of the wild type TetA gene, optimizing and de-optimizing several segments of the coding sequence. Each TetA variant is coupled with a distinctive fluorescent gene, and each pair of genes is flanked by lox sites. In the presence of Cre protein, the lox mechanism either inverts or excises the coding sequence, yielding different combinations of expressed TetA variants. An expressed variant corresponds to an item being placed in the knapsack. Over-expression of TetA results in cell death, which represents exceeding the capacity of the knapsack. Under-expression of TetA causes the cells to stop growing due to tetracycline in the growth medium, which represents not completely filling the knapsack. Surviving cells correspond to cells within a certain range of TetA production and the fluorescence tag allows for comparative measurement within this range.

The team is also working to develop software tools relevant to the specific project and applicable to projects in the wider synthetic biology community.

We optimized the codons for a portion of the TetA gene in order to produce variant genes that confer differing amounts of tetracycline resistance. We also created 11 variant lox sites that have differing recombination frequencies. Finally, we explored gene expression of RFP and the TetA gene.

Lab notebooks are an integral part of conducting scientific research because the results of a scientific experiment must be reproducible. In an effort to properly document our efforts, each team member kept a detailed record of their daily activities. We have condensed the information from all of these sources so that each entry in this virtual notebook contains the highlights of each day’s work. View the daily progress of our project via the lab Notebook.

Parts

Parts

BioBricks are the foundation of iGEM. We have created more than 40 basic and composite parts that are now available for the entire synthetic biology community to use. Among these parts are 11 new variant lox sites in both forward and reverse versions. Using these variants, we have constructed “modules” consisting of RFP floxed by multiple different combinations. Furthermore, we have assembled new cre recombinase expression cassettes and added them to the RFP modules. View the parts built by our team.

This project and our participation in iGEM 2010 would not have been possible without help from numerous sources. We have received invaluable assistance from numerous people both at Davidson College and at Missouri Western State University. Furthermore, many organizations have contributed generously to our efforts, and without their help, we could not have come this far. This section is a thank you to our sponsors and all of those who have helped us in any way.
