We run a a 62ns simulation on the 2v0w light state using 32 processors. Here is a video.

Validation of the simulation

Here are the values of pressure, temperature and volume for this run.

The rmsd along the run gives:

And the rmsf is:

Analysis of the simulation

As for the dark state, we tried to find a change in the j-alpha helix then looked at the comportment of the residues.

We ploted the angle between the helix and a strand of the beta sheet. As in the light state we don't see a clear movement.

We also redid the same experiments as in the dark state. Here is the plot of the dihedral angle of GLN513 and ASN414. In this case, both residues don't switch to another conformatinal state.

An interesting residue to study in the light state is the residue n° 450, which is the cystein that reacts with the cofactor. Here we plot the dihedral angle of this residue to see how many time the cystein point toward the FMN. As expected, the residue is now stable because of the covalent bond to the FMN.
