The HIV Protease Database is an archive of experimentally determined three-dimensional structures of Human Immunodeficiency Virus 1 (HIV-1), Human Immunodeficiency Virus 2 (HIV-2), Simian Immunodeficiency Virus (SIV) Proteases and their complexes, serving a global community of researches, educators, and students. There are two main parts of the database:

• Informative Part
  This section contains information about the structures of complexes, inhibitors, enzymes, unique names of the compounds, references and some images.
• Analytical Part
  This section contains some results of various analyses and tools customized for user purposes (fitting structures, converting structure files, measuring, etc).
