== '''What we want to do''' ==
 
-
 
-
Light-sensitive proteins can easily be found in nature, but they have never been cloned into other cells. In this project, our aim is to design a fusion protein that would allow genetic regulation through light control.
 
-
 
-
Therefore we are working on cloning strategies that would allow us to fuse a light-sensitive domain (LovTAP in our case) with a regulatory domain (like the Trp operon). The idea is to allow transmission of the conformational change induced by light (on the light-sensitive domain) to the DNA-binding domain. This transmitted conformational change would then result in an increase or decrease of the regulatory domain's affinity for the DNA promoter site.
 
-
 
-
The overal effect would thus be a genetic expression controlled by light! There would be many applications to such a "switch" : it could kill bacteria at a certain point, stop their growth, or make them express specific proteins...
 
-
 
-
To improve the change induced by light (which is generally very unstable), we also plan a modeling part where the aim is to find which residue we would have to mutate in order to have a stable protein after the switch.
 
-
 
-
The advantage of such a system is that we could apply the light on a system and then remove it (not like if we added some liquid on the cells).
