The recombinant vaccinia virus - expressed mutant P1 polyproteins were analyzed for proteolytic processing defects in cells coinfected with a recombinant vaccinia virus ( VVP3 ) that expresses the poliovirus 3CD protease and for processing and assembly defects by using a trans complementation system in which P1 - expressing recombinant vaccinia viruses provide capsid precursor to a defective poliovirus genome that does not express functional capsid proteins ( D .
