This is something you would normally not do in the course of refining a protein structure, because the structure would no longer correspond to the observed structure factors and no longer be consistent with the symops of the particular space group. There are applications for it in

thanks. i may mean something other. for example, if i rotate the pdb by 30 degree (or 29.5 degree), or i shift the pdb along x-axis by something for example 0.123*a, then how i move the mtz map correspondingly for the fitting of mtz into the transformed map? | | Smith Liu | |

Assuming you have a good reason for doing that, I'd suggest the best approach would be to first generate a real-space map covering your original coordinates, and then apply the transform to that. To transform a volumetric map, all you're actually transforming is the (x,y,z) coordinate of its

If you use coot with on the fly map calculation (e.g. you load an mtz and not a map file), you do not need to transform the map. Otherwise I would recommend to run one more round of refinement and produce a new map your usual way. This will also get rid of any rounding errors due to the

Well, yes, a one-liner to move every atom to 1,1,1 would be: awk '! /^ATOM|^HETAT/{print;next} {print substr($0,1,30) " 1.000   1.000   1.000" substr($0,55)}' whatever.pdb > ref.pdb Which I suppose is a bit of a long one-liner, but still only one line.  The next line would be a call to

HI Jiyong, If you still have protein left, you may try to sequence it. In some cases, even N-terminal digestion is very helpful. In my previous, I always got a 90KDa protein, which was very close to my target kinase. Based on the protein sequencing, we identified it was one of those chaperones.
