in order to promote the production of new virus particles ,
as well as to evade the cellular antiviral immune responses .
These proteases perform the posttranslational proteolytic processing of the viral polyprotein , but they also cleave several host - cell proteins in order to promote the production of new virus particles , as well as to evade the cellular antiviral immune responses .
