The genes express large polyproteins that undergo proteolysis to form several nonstructural proteins … Zobacz więcej ORF1a is the first open reading frame at the 5' end of the genome. Together ORF1ab occupies about two thirds of the genome, with the remaining third at the 3' end encoding the structural proteins and accessory proteins Zobacz więcej Core replicase domains A set of five conserved "core replicase" protein domains are present in all nidovirus lineages ( Zobacz więcej The polyproteins pp1a and pp1ab contain about 13 to 17 nonstructural proteins. They undergo auto-proteolysis to release the nonstructural proteins due to the actions of internal Zobacz więcej The structure and organization of the genome, including ORF1a, ORF1b, and the frameshift separating them, is conserved among nidoviruses. Some "non-canonical" nidovirus structures have been described, mainly involving gene fusions. … Zobacz więcej
