That's what I needed. For some reason, I had thought those commands worked differently on the model rather than chains but I tested what you wrote and it's what I need. </div>

Hello David!<br>
This answer is for ChimeraX:<br>
<br>
To move something some exact number of angstroms or degrees, you would use commands. The "move" (translate) and "turn" (rotate) commands each have an "atoms" option to specify moving only certain atoms, in this case one of the chains in your structure. In
the commands, you can also specify the direction of movement, axis of rotation, center of rotation, etc.<br>
<br>
See help pages with the ChimeraX command "help" (e.g. "help move" or "help turn") or see the copies at our website here:<br>

<br>
Example:<br>
open 1zik<br>
show atoms<br>
name protb /B & protein<br>
move y -20 atoms protb<br>
turn z 35 center /B:14@ca atoms protb<br>
<br>
I hope this helps,<br>
