Sandbox423
This sandbox is in use until August 1, 2011 for UMass Chemistry 423. Others please do not edit this page. Thanks!
Team & Structure selection, due 4/1/11: All projects & names must be posted on the list below, linking to sandbox pages displaying initial structure.
- Form teams of 4 people; include both chemistry and chemical engineering majors on each team. Start by finding a protein-drug or nucleic acid-drug complex with a known structure that interests your team (see assignment sheet instructions). Check the list below to see if another team has already chosen this complex. If not, start a new sandbox page (just try sandbox## in the search box to find an unused number) and add a link for your team/protein to our class list below (use editing button above (Ab) or follow my model).
- Copy the message at the top of this page into your sandbox page to "reserve" this sandbox for this course.
- Find the pdb id for your protein-drug complex in the Protein Data Bank. In your sandbox page click"edit this page" (top) and follow the directions to insert your rotating structure on your page.
Project completion, due 4/22/11 Your proteopedia page should be organized into the following 4 required sections, with each team member responsible for one of these sections of the team project.
1. Introduction
- Introduce the protein function and the disease treated by the drug. This must be written in your own words with citations to your sources.You cannot include a copyrighted figure unless you request permission to use it.
2. Overall structure
- Describe the overall structure of your protein in words and make "green scenes" to illustrate your points. What elements of secondary structure are present (ie 5 alpha helices and 2 beta strands) and how are they organized? Below I illustrate the start of an "overall structure" section on GFP. 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.
3. Drug binding site
- Describe features of the drug binding site in words and make "green scenes" to illustrate your points. Show the interactions that stabilize binding of this molecule to the protein (ie H bonds).
4. Additional features
- 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).

Some of the above are for help editing Wikipedia pages, but the syntax is mostly the same. Proteopedia ADDS protein stuff to the WikiMedia markup language, which powers both WEB sites.
