While certainly a fantastic educational resource, the San Diego Supercomputer Center (SDSC) website is definitely geared towards those with a background in or who are currently studying proteins. The site, authored by Eric Martz of the University of Massachusetts, offers several flash-enabled movies that allow viewers to study protein molecules from a three dimensional point of view. As the site notes, "for visualizing the three-dimensional structures of protein, DNA, and RNA macromolecules, and their interactions and binding of ligands, inhibitors, and drugs. It is arguably the easiest-to-use software of its kind. It is suitable for high school and college students (ages 16 years and older), yet it is also widely used by graduate students and researchers." Thus, beginners to the site will want to check out the Beginners Start Here section so not to get too overwhelmed with the many other areas of the site.
