Production of polyprotein fragments (so called replicase proteins) involves the repeated autocleavage of the polyprotein, liberating the two endopeptidases that finally cleave all fragments efficiently. Only nsp3 and nsp4 are post-translationally modified, they are glycosylated (Muramatsu et al, 2015; Harcourt et al, 2004; Oostra et al, 2007)
