We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

As life is more than 2D, Proteopedia helps to bridge the gap between 3D structure & function of biomacromolecules

Proteopedia presents this information in a user-friendly way as a collaborative & free 3D-encyclopedia of proteins & other biomolecules.

HIV-1 protease

by David Canner
The X-ray structure of HIV-1 protease reveals that it is composed of two symmetrically related subunits which form a tunnel where they meet. This is critical because it contains the active site of the protease, consisting on two Asp-Thr-Gly conserved sequences, making it a member of the aspartyl protease family. The two catalytic Asp's either interact with the incoming water or protonate the carbonyl to make the carbon more electrophilic for the incoming water.

Structural flexibility of the periplasmic protein, FlgA, regulates flagellar P-ring assembly in Salmonella enterica.

H Matsunami, YH Yoon, VA Meshcheryakov, K Namba, FA Samatey. Scientific Reports 2016 doi: 10.1038/srep27399
A periplasmic flagellar chaperone protein, FlgA, is required for P-ring assembly in bacterial flagella of taxa such as Salmonella enterica or Escherichia coli. Here we present the open and closed crystal structures of FlgA from Salmonella enterica serovar Typhimurium, grown under different crystallization conditions. An intramolecular disulfide cross-linked form of FlgA caused a dominant negative effect on motility of the wild-type strain.

Eastern Equine Encephalitis virus
Although only a few people in the USA get Eastern Equine Encephalitis every year, the fatality rate is 30%, and many survivors have ongoing neurological problems. The virus is transmitted by mosquitoes from animals, especially birds, to humans. This RNA virus has a complicated capsid (a slab of which is shown) composed of protein shells with an enclosed lipid bilayer. The structures of virus capsids can be explored using free FirstGlance in Jmol.
