Spanish flu virus antigen. Computer model showing the molecular structure of a haemagglutinin 1 (H1) antigen from the Spanish influenza (flu) virus particle. Alpha helices (coils),beta sheets (arrows) and linking regions (thin,wire-like) can be seen forming the quaternary structure of the spike-shaped surface protein. Haemagglutinin binds to host cells,allowing the virus to enter them and replicate. This virus was responsible for the 1918 flu pandemic | |
