[Chimera-users] Show molecular surface for one chain only

[Hurt, Darrell (NIH/NIAID) [E]]

Hi Chimera folks,

I have a peptide bound to a protein. They are two separate chains in single PDB. I want to show the molecular surface for the protein, but not the peptide (to see the surface where the peptide binds to the protein). This is easy (the default, actually) for small molecules. But when I select the chain of the protein and display its surface, the surface is "broken" around the peptide and I cannot see what I want. The rest of the surface is OK, but in the area of interest, I cannot see the surface.

I tried the "Intersurf" command and it sort of works, but I want an MSMS molecular surface of the protein with the peptide sitting in it. Is there some trick for this other than separating the peptide from the protein and putting it into a separate model?

Thanks,
Darrell
