- | <p> The <em>Nuclear Fusion</em> project | + | <p> The <em>Nuclear Fusion</em> project involves a plasmid construct very generously donated to our iGEM team from David W. Wood, Department of Chemical Engineering at Princeton University. Research in their lab has constructed a biosensor containing just the ligand binding domain (LBD) of the estrogen receptor (ER). Our plan for this project is to work on the sensitivity of the biosensor in hopes of using this for water prescreens, similar to the <em>Smart Fold Reporter</em> project. The sensitivity will be focused for BPA which has a very different conformation than the natural agonist of the ER system (estradiol). This difference causes BPA to bind weakly but still disturbs normal ER function.</p><p>We intend to analyze the LBD of ER and perform directed evolution to increase BPA sensitivity. During directed evolution, certain regions of the ER LBD would be targeted for random mutagenesis providing a library of mutants in the trillions. The mutant library would be induced with BPA and the best growing colony would be selected, tested, and mutated for further sensitivity.</p> |

PENN STATE iGEM 2008
Welcome to the Penn State iGEM 2008 team’s website. We are currently working hard at a few different projects for this year's competition. In early May we began brainstorming and came up with a couple of ideas to create biosensors that use human nuclear hormone receptors to recognize potentially harmful ligands. These receptor systems occur naturally in the human body, but our goal is to retain and utilize their functions in Escherichia Coli. We are also finishing up one of last year's projects which is aimed at creating a more efficient bioproduction process by altering how E. Coli selects between the utilization of 5 and 6 carbon sugars. Please explore our website to find out more about us and our projects! If there are any questions or comments about the information on this site please contact us at gjt5001@psu.edu.
