## [PyMOL] Rotation of entire helix

 [PyMOL] Rotation of entire helix From: Alex Truong - 2012-10-26 20:32:10 Attachments: Message as HTML ```Hi All, So I have a structure that's fully modeled, but I have one alpha helix that is turned in a non-optimal way. Is there anyway to "rotate" the entire helix along its barrel while keeping everything else fixed? The objective is to turn it such that a critical side chain that was facing inward is now facing outward. The helix itself is quite short and is flanked by relatively spacious loop regions, so the overall structure would (theoretically) not be affected too much. In theory, it seems simple, but in practice...I haven't been able to figure out a straightforward way to do so. Any ideas or suggestions? Thanks, Alex ```

First, use the rotate command: # rotate the selected atoms 4.5 degrees about the x axis. rotate x, 4.5, (sele) If you specifically know the axis of rotation, supply it as a vector. Next, PyMOL can also do rotations about an axis defined by two picked atoms. In editing mode, just pick the terminal atoms and hold down the left mouse button and CTRL while dragging.
