I would like to draw some H-bonds between the ligand and the backbone nitrogen and carbonyl oxygen. The protein is shown in cartoon and the ligand and other side chains are shown in stick. "Side chain helper" is on. How can I show the carbonyl oxygen as a stick? What is the best way to show the backbone nitrogen?
