Dear all I am having trouble with an unnatural ligand/amino acid.
I have a structure very similar to PDB 6Q6H, 7TQR. They all have an MDO residue that replaces three residues in a series G-A-S-G-D to become G-MDO-D. MDO is in the Coot library. I have been very used to replacing cysteines with CME with Modelling>Replace residue. It works great, removes the OXT and all the other atoms, can use real space refine directly. For this MDO residue I find that it correctly fetches from the dictionary, however, I cannot refine it. Whenever I click on an atom and drag it just blows up or the atom gets stuck. I have now opened up 6Q6H and 7TQR and tried to just refine the built in MDO in those PDB, same thing happens. Does anyone have any ideas of what might be going on? Also in general for modified residues/unnaturals. ######################################################################## To unsubscribe from the COOT list, click the following link: https://www.jiscmail.ac.uk/cgi-bin/WA-JISC.exe?SUBED1=COOT&A=1 This message was issued to members of www.jiscmail.ac.uk/COOT, a mailing list hosted by www.jiscmail.ac.uk, terms & conditions are available at https://www.jiscmail.ac.uk/policyandsecurity/
