Molecular Coordinate Files
(Optional)

Below are several coordinate files. You will need the chime plug-in. The computers in the library usually have it installed. If you want to install it on your own computer, click here to download chime, which is free. (Download the file to your desktop, close browser, then open file.).

Once a molecular coordinate file below is open, move the mouse pointer over the molecule and use the left mouse button to rotate molecule. Use the right mouse button to see menu for changing the style of representation. {MAC users: hold down mouse button to see menu.} For example, try the spacefill representation. Also, with the shift key depressed, use the left mouse button to zoom.

Select one of the
following molecules:

National Protein Data Bank at Brookhaven National Laboratory has files for thousands of proteins. Use one of the "search" tools to find a protein of interest. You can view the protein at the site via JMole (if your computer has Java) or can download a pdb file to use with Chime. Save the file with a ".pdb" suffix, and then enter the address of file in your brower and open.

(Many files not only include the protein, but also water (indicated by red oxygens) that are part of the crystallography data. To remove these, use the right mouse but to select "options" and specify that "hetero" atoms are not to be displayed.)
