You might also be interested in the supercell http://www.pymolwiki.org/index.php/Supercell pymol script, which generates all chains in the unit cell as opposed to within some radius of the asymmetric unit. -Spencer On Fri, May 22, 2015 at 2:45 PM, Roger Rowlett rrowl...@colgate.edu wrote: If

[ccp4bb] Easy way to generate symmetry-related protein chains?

2015-05-22 Thread Mark J van Raaij
Just wondering if there is an easy way to generate symmetry-related chains, necessary for instance to join protein chains into the biologically relevant multimers. What I do now is look up the correct symmetry and translation operator in COOT or PYMOL and input that in PDBSET, but there may be

Hi Mark, If the structure has been deposited in the PDB you can download the biological assembly - even works for viruses, cheers, Matt. On 22/05/2015 14:24, Mark J van Raaij wrote: Just wondering if there is an easy way to generate symmetry-related chains, necessary for instance to join

If you mean generation of pdb coordinates of specific symmetry chains (not just viewing) then you can do this with the symexp command in pymol. Select the desired symmetry partners and save as pdb. You may want to edit duplicate chain id labels in coot or a text editor. Roger Rowlett On May 22,

It seems the easiest way is to Save Symmetry Coordinates in COOT and then assemble the desired chains in a text editor. Extensions - Modelling - Symm Shift Reference Chain Here. is present if you build COOT yourself, but is not in the pre-built releases (for now). Mark J van Raaij Dpto de
