5. enterovirus(English)

   • small naked virus belonging to the family Picornaviridae. The genome consists of a unique molecule of single-stranded RNA of about 7,500 nucleotides in length. This genome is positively stranded, i.e. it is directly used as a mRNA by the cellular machinery. It contains a large open reading frame that is translated into a unique polyprotein, which is subsequently cleaved to give rise to the functional proteins. The 5’ part of the ORF encodes the four proteins that form the capsid (VP1 to VP4); downstream, the genome encodes different proteins that are involved in the virus cycle. Five types have been described within the species Enterovirus D
