Hi Claire,
All you need to do is:
1) Create selections for the two atoms you want to H-bond. There are
several different ways to do this in PyMOL (see the manual for details),
but for example, to bond
chain A, Thr 15 OG1
chain D, Asp 184 OD1
you would do
select donor, A/15/OG1
select acceptor, D/184/OD1
2) Create a h-bond object between these selections. The easiest way is
to use PyMOL's "distance" command which draws a dashed line between
them. It also shows the distance as a label, but you can turn this off
distance hbond, donor, acceptor
hide labels, x
3) Play with the settings to get it to look how you want. Dashed lines
sometimes look a bit odd when you ray-trace them - I find that
set dash_length, 0.15
set dash_radius, 0.09
set dash_width, 3.00
looks good. You can put these commands in your .pymolrc to save typing
them all the time.
Hope that helps,
Gareth
