Cool Video: HIV's Inner Shell
June 20, 2013

The cone-shaped HIV capsid is composed of about 1,300 copies of the protein p24. Those proteins are arranged into a coat of hexamers (shaped like hexagons). The arrangement of 12 p24 pentamers (shaped like pentagons) allows the hexamer coat to curve and close the structure. Surrounding the capsid are spheres, which represent charged particles from salts used in the analysis. This video comes from a computer reconstruction of data from the researchers. Credit: Juan R.
