You will familiarize yourself with the structure of EF-Tu and locate the substrate analog GNP in the active site. Look under each heading and familiarize yourself with the transformations that are accessible from this menu. Use of this command window and commands described below will be essential for allowing you to look at various parts of the structure of EF-Tu. Let's first look at some features using the current view. The view can be changed under the pull down menu Display .
Backbone deletes all sidechain atoms.
Sticks essentially provides the same view as wireframe but with cylindrical bonds Spacefill magnifies all atoms to their Van der Waals radii. For EF-Tu there is only one peptide chain, so it will be one color. One can zoom in by depressing the shift key and left hand mouse button and moving the mouse forward or backwards. You can move the molecule in a translational sense by depressing the right hand mouse button and moving the mouse in any direction. To rotate the molecule around its Z-axis, depress the shift key and use the right mouse button while moving the mouse.
