Rotate chain

[Anonymous]

 

I have a pdb with a homodimeric conformation for two alpha helix transmembrane domains.

This structure features a cross-like conformation, interacting at known residues.

I want to rotate each of the domains 15º along the z-axis

So for exmaple, something like this would be fine:

 

select :.A                 (select chainA)

turn < 15 @ca,cb    (rotate chain A 15º, from the residues given as an anchoir point)

 

is there anything like this? Thx

Hello,

What you want to do appears to be relatively easy using the RollMover, have you tried that?

https://new.rosettacommons.org/docs/latest/scripting_documentation/RosettaScripts/Movers/movers_pages/RollMover

(i have never used the RollMover before but I assume it will work)

 

If the RollMover does not suit your needs, I would suggest trying to solve your problem in pyrosetta rather than via rosetta_scripts XML!

Thanks a lot @danpf

I ‘m executing this script

      $rosetta3/bin/rosetta_scripts.default.linuxgccrelease -s tm_dimer.pdb -parser:protocol roll_mover_integration.xml

With this xml:

     <RollMover name=”randomroll” start_res=”1″ stop_res=”30″ min_angle=”0″ max_angle=”-90″>

             <axis x=”34.910″ y=”33.490″ z=”50.200″ />

             <translate x=”0″ y=”0″ z=”0″ />

It seems to work properly. If I understand it correctly, the axis determines the point at which I want to make the rotation, in this case, x, y and z correspond to an atom of the residue where the rotation occurs, and translate remains at zero since i don’t want to carry out any translation.

However, for 70 degrees of rotation, the change in tilt of the chain is very small, why is this?

I’m also getting several warnings:

I guess the atoms that are discarded correspond to hydrogens, in which case they can be added later, it’s also removing two residues, what can I do about it?

 

Thx again

Hello,

I’m not sure why youre 70 degree angle change is only appearing as a small angle change.

Since it does not seem to work easily out of the box, I will again suggest switching to pyrosetta.

XML based rosetta_scripts are amazing for a lot of things, but very specifically manipulating poses is usually best done in pyrosetta.

 

As for the removed two residues : Rosetta is unable to build residues that are missing an N, CA, or C atom.  It would appear that your input pdb file is missing one of those atoms  for two residues.

EDIT: I would try removing the hydrograns for the residues that are on the residues that are getting deleted. I think it might be messing with how rosetta is reading the residues
