I added zinc manually in the text version of the pdb file: have a look at other crystal structures that contain zinc and copper, and see how they specify the coordinates in the text file. Do the same in your one and hopefully it will work!! Good luck Martina Date: Thu, 23 Oct 2014 13:36:33 -

Dear you all May I ask a question? I tried to dock my protein structure onto an cryo-EM density map. I loaded both the map file and my model coordinates into Chimera. But it looks apparently that they are not in the same size scale. My model is much bigger than the size of the EM map region wh

There is a bug in version 0.7.2 Coot that causes metal ions added via the "place atom at pointer" to be a water. However, if you add the metal ions through the "Get Monomer" dialog I think it will work OK. ___ Roger S. Rowlett Gordon & Dorothy Kline Professor

Thank all of you! I have not " change the residue numbers so they do not overlap", so the "change chain IDs" doesn't work when I try to change chain ID to an existed chain ID. Edit the PDB file is another good idea but when I have 20 SO4 in 20 chains, things become boring. Best wishes

Molprobity does not look at contacts from symmetry partners, but only at the asymmetric unit ones. Unfortunately the clash scores in the PDB validation reports are based on Molprobity and thus they won't count clashes outside the AU. See for instance structures 4bmw or 1jkm. Both contain serio

Dear Lu, You could do this in Coot as well if you are uncomfortable doing this in a text editor. First change the residue numbers so they do not overlap, then change the chainID. Rather than putting all your sulfates in a separate chain, it is better to add them to the correct protein chain. PD

Dear Lu, - you could just edit the pdb-file by hand in a suitable texteditor (which is what I usually do, in MacOSX TextEdit). - smarter people may find a functionality in COOT, PDBSET or other existing program that can do it. - even smarter people would probably write a script or little program
