Wonderful. I'm close to completing what I need, thanks a lot. I have one other question here. Say I have a peptide: N-Ala-Ala-Glu-COO (I'm just pointing out the terminal amide and carbonyl groups). Then I protonate it with h_add H2N-Ala-Ala-Glu-(C=O)H. Now I carry out a mutation on the last

Hi Martin, atoms within less than VdW distance. Is there an easy, very low-level, PyMOL way of fixing this? Can the sculpting wizard be used for this? Yes, after you place the sidechain and have the new structure (via the apply function) you can then apply sculpting. It would look something

Martin, I am wondering, are there any scripts/ plugins for PyMOL out there that facilitate the generation of a large amount of rotamers for different mutants? I might take the effort and start building this into a plugin. I'm not aware of any. Some of our other seasoned PyMOLers might,

These are all great ideas--I'm glad I asked. I updated the wiki page (http://www.pymolwiki.org/index.php/Aa_codes) to reflect this discussion. Cheers, -- Jason On Mon, Sep 13, 2010 at 4:17 AM, Tsjerk Wassenaar tsje...@gmail.com wrote: Hi Jason e.a., I usually do the hashing like: aa1 =

Hi all I want to do some scripted mutations on a range of residues. Say I want to mutate residue 189 to every rotamer of [Asp, His, Glu, Thr, Lys] available in the PyMOL internal rotamer library. I'm seeing that PyMOL issues cmd.get_wizard().do_state(i) to select rotamer 'i' for a mutation.
