The Team
| METU_IGEM team was established by the 4 undergraduate students one year ago with just the effort of these student. Then 2 members participated. After 2007 competition, thanks to the advises of old four members the recent team was formed. The team composed of 16 undergraduate students majoring in Molecular Biology and Genetics and Biology. We were the first Turkish team which participated in jamboree from Turkey. Hence we also wanted to be the first awarded Turkish team.
The ProjectWe design a system for the metal carrying. In our system, there are two light sources. One of them is for the metal source and another is for the destination to where we want to carry metal atoms. And our machines have phototaxis ability. In addition to this, they have metal binding domain in outer surface and bacteriorhodopsin. When we open light at the metal source, they start to move toward there and catch the metal atoms. Then we open the light at the destination while closing the light at the source. So our machines move toward the destination. After the arrival our machines will be exposed to light with specific wavelengt to activate bacteriorhodopsin leading to small local pH changing at the outer surface. This pH changing causes the release of metal atoms from the metal binding domain. Finally, system starts from the beginnig and so on. As a result we will make E. coli cells act as trucks that carry metal ions on our medium from the metal uptake location to the release locations and also the path are illumintated by lights at specific wavelenghts. |
