[PyMOL] surface representation of the protein-ligand interactions

[Enrico M. <jms...@gm...>]

Dear Pymol users!
Working on the vizualisation of the protein-ligand interactions I
would like to switch from cartoon to the surface representation of the
protein, while still being capable to see the ligand-binding cavity
(as well as non-covalent interactions)

Could you suggest me some combination of the options which could helps
me with such vizualisaiton?
I have alread tried
show surface, all within 5 of my_pdb and not polymer
set surface_smooth_edges, onset surface_smooth_edges, on
where my_pdb and not polymer corresponds to the selection of the ligand

Eventualy this create cool surface representation of the protein and
but completely hides the ligand-binding cavity
Many thanks in advance!
Enrico
