In our project, KillerRed is the new part that we have to study in order to determine its potential effects. Before working with the actual DNA, <a href="https://2013.igem.org/Team:Grenoble-EMSE-LSU/Project/Biology">documenting</a> ourselves on the protein was necessary.<br>

<p>In the case of KillerRed, the function is that of a fluorescent protein similar to EGFP or dsRed, but with photosensitizing properties increased 1000-fold. EGFP is used in many research applications as a reporter protein but is actually slightly toxic.[1,2]<br>

This phototoxicity is due to ROS (Reactive Oxygen Species) generation. This ROS generation is only possible with the presence of molecular oxygen as an electron donor [3,5]. with superoxide being the main ROS generated, and the main source of KillerRed's phototoxicity [3]. ROS are extremely unstable compounds that readily react with many substrates including lipids, proteins and DNA [4]. There are many possible reactions and most if not all damage the substrate, leading to cell death. Reactions with DNA can also lead to mutagenesis and it was necessary to take this risk into account when working with the protein.<br>
