Modeling

To do

- Model allosteric interactions between LOVTAP & TrpR

What will be done:

- Model of LOVTAP in dark phase

- Model of LOVTAP in light phase

- Characterize how the J-alpha helix changes

- Model sturctural changes that enhance the switch feature of LOVTAP e.g. in dark phase: really weak interaction between LOVTAP and the corresponding DNA sequence, in light phase: strong binding of LOVTAP on DNA.

We will follow the following article protocol:
Freddolino, P.L., Dittrich M., Schulten K., Dynamic Switching Mechanisms in LOV1 and LOV2 Domains of Plant Phototropins. Biophysical Journal, 91, 3630-3639, 2006 (Pubmed)

- Model the fusion of LOV domain with other transcription factors

To envisage

- Molecular mutationnal assay

Already done

We generated all the files needed to do the simulation, thanks to the tutorial of NAMD, which can be found on the following page:

Here is our first movie from the modeling, showing the behavoir of the protein in the dark state condition: 2v0u_dark_state.mov
