Spanish flu virus. Computer model showing the molecular structure of an H1 antigen from a Spanish flu virus particle. Alpha helices (coils),beta sheets (arrows) and linking regions (thin,wire-like) can be seen forming the quaternary structure of the viruses protein coat (capsid). This virus was responsible for the 1918 influenza pandemic. The membrane envelope of influenza viruses is studded with many spike-shaped proteins,including haemagglutinin,that enable it to attach to and infect host cells | |
