hello-
i am new to pymol and am trying to figure out how to differentially
color different chains (i.e. different proteins) in the structure i am
viewing. the structure i am working with is actually a structure of
two
proteins that were co-crystalized and i would like assign different
colors to them.
thanks for your help.

Hello Alex, I think what you want is to use the 'select' function in
combination with the 'resi' function. This is documented in the
reference manual.
Following is a helpful summary that was sent to me by Robert L.
Campbell, Ph.D.
Let's say I wanted to create a single residue selection for Lysine 465
(and I choose to call the selection 'K465'), so that I could color and
display it the way I wanted: (insert your particular atom coordinates
file name where you see square brackets below)
_______________________________________
select K465, ([filename] and chain A and resi 465)
or you could shorten the selection string:
select ak465, (abc & c. a and r. 465)
or use the shorthand notation:
select ak465, /abc//a/465
_______________________________________

Now to create multiple residue selections, just separate the start and
end residue numbers by a colon, I think, following the word 'resi'
Once you create your unique selections they show up in the right panel
list and you can further manipulate their display properties as you see
fit.
