The X-ray structure of HIV-1 protease reveals that it is composed of two symmetrically related subunits, each consisting of 99 amino acid residues. The subunits come together in such as way as to form a tunnel where they meet. This tunnel is of critical importance because the active site of the protease is located in its interior. The active site consists of two Asp-Thr-Gly conserved sequences, making it a member of the aspartyl protease family. The two Asp's are essential catalytic residues either interact with the incoming water OR protonate the carbonyl to make the carbon more electrophilic for the incoming water. (more...)
November 2024: How To Find A Structure is a new guide to finding an empirical model for a protein of interest, choosing which empirical structure is best, and getting an AlphaFold-predicted structure when no empirical structures are available.
March 2024: Professors are using Proteopedia for class projects in Brazil, Czech Republic, France, and various states in the USA. See the updated Adoptions in College and University Classes.

A practical guide to teaching with Proteopedia [1]
June, 2016: Proteopedia uses the Biological Assemblies from PDBe as the default scenes for all PDB entry pages. Thus, based on the curation by EBI (host for PDBe) the most biologically significant structure is shown.
