03/02-- The dengue virus – the first flavivirus structure to be determined – reveals an architectural structure that is different from any other virus that has been seen, says Purdue University researcher Richard Kuhn. The virus surface is unusually smooth and its membrane is completely enclosed by a protein shell. This computer illustration shows how the major protein, called "E" for envelope protein, organizes itself to form a protective shell around the virus. The protein is color-coded blue, green and yellow to show the three specific domains of the protein. The protein shell serves as a cage for the genetic material inside.
