In the command line (show from Favorites menu) you can easily specify the chain ID along with residue name or number. For example, command:
— or —
...selects the GLC residues in chain E only. You don’t have to capitalize the residue name or chain ID.
Two alternative methods:
(1) if you want to use menu only to select these residues, it is more steps. Menu:
Select… Residue… GLC
Select… Selection Mode… intersect
Select… Chain E
Select… Selection Mode… replace
(the last one just puts the selection mode back to normal so you wouldn’t get confused later).
(2) of course, if it is already displayed you can select it with Ctrl-click on one of its atoms or bonds, then pressing keyboard up arrow to select that whole GLC residue, then if you want the whole oligosaccharide (more than one GLC bonded together), press keyboard up arrow again
I hope this helps,
