How far apart are the SG atoms?
Do you have SSBOND records in your PDB file?

Dear all,
I have a problems displaying disulphide links in PyMoL and CCP4mg for a 2.3 angstrom crystal structure. I have tried both PyMoL and CCP4mg, these programs are not recognizing an important inter-domain disulphide bridge which seems to have no problems in "Coot". While other intra-domain disulphide links are fine. Can anyone suggest how to manually fix it?
In addition, I have performed protein-protein docking using this crystal structure and have obtained nice convincing model. However, in this pose, which is being refined and energy minimized, none of the disulphide links are intact! Upon manual examination, I have noticed that the corresponding cysteine are 3.0-4.0 angstrom away. How should I correct this?
Looking forward to your suggestions...
With thanks and regards,
Urvashi
