# How to show electrostatic interactions in Pymol on the wanted residue

I have the following Pymol visual, The green molecule is receptor and red/yellow is the ligand. In the ligand I highlighted Lysine (K) residue as yellow.

What I want to do is to highlight and draw the electro static contact of the ligand especially with Lysine residue. Like this in Pymol:

How can I achieve that?

• Thanks but I'd like to see the electrostatic contact - proton and electron - like shown in my OP. Oct 31 '21 at 11:10
• This answer is still valid, you simply click the hydrogen not the nitrogen for your distance. However, I would suggest that you do color atomic, not element C as you currently have all elements coloured in and it's well confusing... Nov 1 '21 at 9:56
