Hi James, the modeling capabilities of PyMOL are rather limited, there are probably more powerful tools for such tasks.
Without guaranty that the result will be reasonable, try this: # lock all but the STG tripeptide protect not pepseq STG # activate sculpting sculpt_activate all set sculpting # switch to edit mode edit_mode Now drag atoms with the mouse or pick bonds and use commands like "torsion". Hope that helps.
