There is a simple way to manipulate part of a protein structure, but
it will not make smooth connections between the moved part and the
rest of the structure.
Take a look at the "Movement Mouse Mode" tool (under Tools... Movement
in the menu). You could either choose "Move helix, strand, or turn"
if you can accurately grab the helix you want with the mouse, or
select your helix and choose "Move selection."
I hope this helps,
