Tsjerk,
 
Nice point, and probably easier to just create new objects in Pymol.

Hi Tiger,

Nick is largely right. The cause for the link to show up is that pymol just traces through all c-alphas in the object, regardless of chains or distances. So, selecting the linked residues and hiding the trace should solve your problem. Also, creating two files will do the trick. Alternatively, you can create two objects and draw the trace for each of these.

Cheers,

Tsjerk

Tiger,

I am no expert by far, but can you select the linkage?  If so, just select
and hide.  Also, you might try just hiding the two residues that are linked,
this might get rid of the link and you probably wouldn't notice the missing
residues unless it is a small protein.  alternatively, and probably the best
solution is to edit the pdb file to create two individual files, one for
each dimer (this can be done in any text editor).  then open both in Pymol
and you should then be able to edit independently.

The problem may be, and again I remind you that I am no expert, that these
atoms are two close to each other and may be getting mistaken for a covalent
interaction, can't tell without actually seeing though.

Hope any or all of this helps.  Good Luck!



Cheers,
Nick
