Modify Molecule Structure in PyMol

This section provides a tutorial on how to modify a molecule structure by rotating and translating a substructure selected from the molecule in PyMol.

Selections in PyMol can be used to visualize substructures differently than the other parts of the molecule. Selections can also be used to modify molecule structure by specifying the selection name in the "rotate" and "translate" commands:

rotate x|y|z degree, selection_name
translate [vector], selection_name

Let's continue with the previous tutorial and modify the substructure defined by the "ring" selection.


PyMOL># show the selection in "sticks" representation
PyMOL>show sticks, ring

PyMOL># modify substructure "ring"
PyMOL>rotate y, 30, ring
PyMOL>translate [1,0,0], ring

The molecule structure is modified now as shown on the screen.
