Provide an interesting and nontechnical description in words, and illustrate points about the complex with green scenes. Be concise: the written description should not extend beyond the jmol window. Do not include any copyrighted figures. All sections must be written in your own words with citations to your sources, following the format in the example below. Make it interesting and accessible to a non-scientist! | ||

What elements of secondary structure are present (ie 5 alpha helices and 2 beta strands) and how are they organized? Additional description and green scenes could illustrate the polar/nonpolar distrubution of amino acids (is the inside of the barrel polar or nonpolar?), packing of amphipathic elements, etc. | ||

:Describe and use green scenes to illustrate additional features of the protein. What you do here depends on what information is available. If a structure of the protein-substrate complex is available, you could compare protein interactions with the substrate vs. with the drug. If the drug is a transition state inhibitor, explain and illustrate that (eg include a reaction scheme with structures of the substrate, transition state and product). | :Describe and use green scenes to illustrate additional features of the protein.

This will include the published paper that describes your structure (the reference associated with your pdb code). You will get much of your information about specific interactions to look for and highlight in the structure from this reference (which is much easier than trying to find these on your own with no guidance!). | This will include the published paper that describes your structure (the reference associated with your pdb code).
