This syllabus is on-line: At proteinexplorer.org click on Workshops, or
http://workshops.proteinexplorer.org/ummed07s.htm

Rationale & Goals: In this day of exploding bioinformatics information from genomics and proteomics, it is ever more important to be conversant with macromolecular three-dimensional structure, and how it relates to protein and nucleic acid function and drug design. This workshop will introduce participants to finding published macromolecular structure data, and visualizing and interpreting 3D macromolecular structure using state of the art, free software. Structural bioinformatics servers will be introduced that yield a wide range of types of key information, yet are easy to use. Authoring tools that facilitate preparation of interactive macromolecular structure presentations, such as those at MolSlides.ProteinExplorer.Org will be taught on the second day.

Software: The central tools for this workshop (all free) are:
FirstGlance in Jmol (firstglance.jmol.org)
and Jmol java applet
  • Operates in all popular browsers and platforms, including Windows, OSX, and linux.
  • Operates on-line only.
  • Open source.
  • Assumes that you are already familiar with basic principles of protein structure.

    Exceptional ease of use. Limited set of "canned" views.

    Adopted by Nature Structural and Molecular Biology and other bioinformatics resources.
    Built upon the free, open source Jmol java applet.
    Protein Explorer in Chime (www.proteinexplorer.org).
    and Chime plugin
  • Operation limited to Windows (including on Intel Mac OS X).
  • Operates on-line or off-line (downloaded).
  • Open source.
  • Much more powerful than FirstGlance: fully customizable images with surfaces. Extensive help and reference materials useful to both students and researchers. Helps you understand and interpret. Won the 2003 MERLOT Classic Award in Biology for exemplary online learning resources: "The Protein Explorer has revolutionized the teaching of biology at a molecular level". Able to build MolSlides. Adopted by numerous bioinformatics resources. Built upon the free MDL Chime plugin (source code not open).

    Level & Pace: This workshop is designed for graduate students and researchers familiar with basic biochemistry, but with no previous molecular visualization software experience. It progresses rapidly to powerful tools that will be of interest to specialists in protein structure and bioinformatics. Experienced participants are encouraged to work at their own speed, ahead of the group -- there is plenty of power to discover within these tools!

    10. Aligning two or more chains or molecules, and how to view the alignment.
      1. The CE site cl.sdsc.edu/ce.html will align any two protein chains quickly and easily (but hetero atoms are discarded, and its database has not been updated since 2001).
      2. DeepView www.expasy.ch/spdbv/mainpage.html can align anything (one or more than one chains), selecting any subset of atoms for the alignment (other atoms following), and retaining hetero atoms. The results can be saved as a PDB file, but will need manual editing to separate models with MODEL [N] and ENDMDL records so that Protein Explorer can distinguish the models. Gale Rhodes provides a DeepView tutorial: click on the section Comparing Proteins.

    11. Homology (comparative) modeling: Introduction.
