Pisoniviricetes
Pisoniviricetes is a class of positive-strand [RNA virus]es which infect eukaryotes. A characteristic of the group is a conserved 3C-like protease from the PA [clan of proteases] for processing the translated polyprotein. The name of the group is a portmanteau of member orders "picornavirales, sobelivirales, nidovirales" and -viricetes which is the suffix for a virus class.
