This Sandbox is Reserved from 15/11/2014, through 15/05/2015 for use in the course "Biomolecule" taught by Bruno Kieffer at the Strasbourg University. This reservation includes Sandbox Reserved 951 through Sandbox Reserved 975.
To get started:
  • Click the edit this page tab at the top. Save the page after each step, then edit it again.
  • Click the 3D button (when editing, above the wikitext box) to insert Jmol.
  • show the Scene authoring tools, create a molecular scene, and save it. Copy the green link into the page.
  • Add a description of your scene. Use the buttons above the wikitext box for bold, italics, links, headlines, etc.

Description

Proteases are one of the 3 (along with reverse transcriptases and integrases) virally encoded enzymes necessary for replication of immunodeffiency virus 1 [3] (HIV-1). The protease is a member of the asparctic protease which cleaves the gag and pol polyproptein from the early life cycle of the virus. This cleavage is essential for the virus maturation to form functionnal small-sized proteins so that it can infect other cells. Without these proteases the virus cannot be infective. The enzyme is a dimer composed of two identical subunits forming a tunnel with the active site inside The mechanism of polypeptides cleavage uses a water molecule [4] as a nucleophile simultaneously with a well-placed asparctic acid acid for hydrolysis of the scissile peptide bond.

The structure of HIV-1 protease with protein bound can't be solved as it would be cleaved before, we analyse how inhibitors bind to the active site to solve the structure

This is a sample scene created with SAT to by Group, and another to make of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes.
