Changing the scene
Surfaces
The "isosurface" command in Jmol draws all kind of surfaces (molecular surface, electron density, orbitals) with all kinds of coloring options (by atom, electrostatic potential, conservation, distance, etc.). It is a complex command, so examples help to learn how to use it.
Electron density
Superpositions
For a Jmol/superposition, you load a file that contains multiple models, or a structure with multiple copies of the same chain in the asymmetric unit. The example below is for multiple models, with model 1.1 and 2.1 sufficiently similar to be meaningfully superimposed. The three dots ("...") in the two select statements should be filled in such that equivalent atoms are selected. In the example scene below, both structures bind to the same ligand.
select 1.1 and ...
show selected
define set1 selected
select 2.1 and ...
show selected
define set2 selected
compare {2.1} {1.1} ATOMS{set2}{set1} ROTATE TRANSLATE
Model 2.1 gets moved and model 1.1 stays in place.
Here is an example, . The Jmol script for the scene is here (see Figure X), and the key command is:
"compare {2.1} {1.1} ATOMS{1000:A and _C}{801:A and _C} ROTATE TRANSLATE"
Use the following buttons to explore the example scene:
Covalent modifications
This script shows carbohydrates and the protein side chains that are covalently linked to them as wireframe.
select within(1.8, carbohydrate) and protein
show selected
select within(group, selected)
select selected and (sidechain or alpha)
select selected or carbohydrate
wireframe on
Because bonds of side chains and modifications are drawn in a single command, the covalent links between them will also be drawn.
Here is an example, , and the Jmol commands used.
