Our project for iGEM 2014 is “<i>Exterminator coli</i>”, an <i>Escherichia coli</i> machine that exterminates insects such as roaches while being completely safe to mammals and the environment.</p><br> |
- | <p> | + | <p>Roaches and many other insects store their energy in the form of trehalose, which can be converted to glucose, when needed, by the enzyme trehalase. However, mammals store their energy in the form of glycogen, which does not require trehalase for conversion to glucose. Trehalase inhibitors can therefore be used as a pesticide that can control roaches while being harmless for mammals and the environment.</p><br><br> |
- | <p> | + | <p>We engineered <i>E. coli</i> that produces the trehalase inhibitor, 3,3´-diketotrehalose (3,3´-dkT), a pesticide that is harmless for the environment and mammals. Our engineered <i>E. coli</i> will overexpress trehalose 6-phosphate synthase (OtsA) and trehalose 6-phosphate phosphatase (OtsB), which convert glucose-6-phosphate and UDP-glucose to trehalose, and glucose-3-dehydrogenase (G3DH), which converts trehalose to 3,3’-dkT. We predict that <i>Exterminator coli</i> will continue to produce 3,3’-dkT even after it is ingested by the insect.</p> |
