Lesson Plans

Four ways to use the PDB ID codes below:

  1. Simply click on the hyperlink below -- it will start Protein Explorer and display the molecule you have selected automatically (provided you are connected to the Internet);
  2. At the FrontDoor of Protein Explorer (, enter the PDB identification code into the slot;
  3. Distribute to your students the PDB identification codes you have selected from the Atlas or elsewhere. (See also Lesson Plans to your right.)
  4. Make a web page of hyperlinks to molecules you have selected in the Atlas. Open free Netscape Composer (or any other HTML editor), choose a molecule in the Atlas, and drag its hyperlink from the Atlas into the Composer. Here are detailed instructions.

To find the primary literature citation for a molecule, the full name and species from which it came, etc., after displaying the molecule in PE, use the resources in PE's Molecule Information Window.

Years in parentheses after links to molecules indicate the years of publication. In some cases a range of years is given: the early year is when the molecule was first solved (if I happen to know that) at 3.5 Å resolution or better; the later year is when the structure chosen for the Atlas was published.

In each category below, PDB files have been divided into those that are relatively straightforward, those that are more challenging, and sometimes enormous. "Straightforward" cases have been selected to avoid complications (such as being NMR ensembles, lacking sidechains, having a nonstandard file format, having many alternative sidechain conformations, etc.).

  Lesson Plans: It is best if your students first have one to two hours to do the 1-Hour Tour to become familiar with Protein Explorer (PE). Then you can assign molecules from the list below to each group of students (or let them pick), and hand out Discovery in Protein Explorer, a generic set of questions, some open-ended. Optionally, you can provide hints suggesting how to use PE to answer the questions. If you use PE in your class, please do the Student Assessment of Learning Gains.

* PDB file sizes marked "*" are given for gzipped files, as they will be transferred from the Protein Data Bank (or other servers) to Chime when the above links are clicked. If you save the plain text PDB file to disk from Chime/PE, it will be about 4-fold larger.
Alpha-carbons only: Some very large structures are supplied as alpha-carbons only. This enables the backbone to be viewed, but not secondary structure (and therefore also not schematic "cartoon" rendering). To see secondary structure, you'll have to get the complete structure (usually available from EBI's Probable Quaternary Structures), but it is typically multiple megabytes in size.
