All hydrophobic side chains are selected. All polar side chains are selected. Next we can use the slab command to 'slice' through the molecule at various positions from front to back. We first reset the zoom position to normal. With the slab commands we will work our way from the front to the back of the molecule.
Predefined Sets are available.
Let's have a look at a graphic view of some of these sets. Single click on the icon above if you wish to check your work. Step Four - Structural Properties Rasmol defines sets for the major structural characteristics of proteins. You can readily isolate the secondary structures in the enzyme using the select command. A ribbon is woven through the backbone of the helices.
