This website is an “Information Portal To Biological Macromolecular Structure”. It is a protein data bank that contains a very large structural database in addition to providing a variety of tools and resources for studying the structure of biological macromolecules and their relationships to sequence, function and disease. A good starting point is to take the tutorial which explains how to use the site and its contents. This site contains meritorious information on biological macromolecules and can be used as a pedagogical resource by teachers, advanced students and practitioners.
