[PyMOL] backbone in cartoon

[Jianghai Zhu]

Hi all,

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?

Thanks.

Jianghai
