MD simulations / Re: DNA screwing into protein

Dear Xiang-Jun,

I would to consider my DNA like a cylinder inside the protein and i would to study how this cylinder rotate referring to the protein.
I'm writing my own script to measure it.
Thank you for your fast reply.

MD simulations / DNA screwing into protein

« on: October 13, 2013, 10:00:20 am »

Hi to all users,
I have started to use 3DNA yesterday. I have to say that 3DNA is a powerfull tool to analyze different and various kind of usefull parameters.
I've run the rubi_script to analyze my trajectories and it works really nice. Just to clarify, I would to suggest you to use TRJCONV (only this)
to convert your trajectories file in a .pdb list, otherwise, the same output will not work properly if you use catdcd or another converter.

Now i would to ask your opinion.
I would to study which is the rotation angle value of my whole DNA molecule that is in complex with a protein.
basically I'm studying Polymerase, WT and Mutated one, to evaluate if that residue is really involved in.
Whit the twist parameter i can't study it.
Someone have any suggestion?

thanks in advance.

Best regards

Vito
