Haemagglutinin protein from the surface of Influenza A virus,molecular model. This protein,known as haemagglutinin,is found on the surface of the influenza A virus. It is responsible for binding the virus to the cell membrane before it enters the cell. There are approximately 500 haemaglutinin molecules on the surface of each influenza A virus. Depending upon the strain of the virus,it can cause human,bird (avian),swine,horse or dog flu. In this model,solid colours represent the secondary structure of the protein (spiral ribbons are alpha helices; arrows are beta sheets),and the faded tubular structure behind represents the individual atoms and bonds | |
