Pokeweed antiviral protein belongs to Ribosome-inactive Proteins. PAP has potent antiviral activity against many plant virus. pT1 was used as the template to amplify the deleted mutant PAP gene (N-deleted and N-,C-deIeted) by PCR and then the two genes were cloned into expression vector. Different IPTG-inducible expression vector containing different deleted mutant PAP gene was constructed and transferred into E.coli strain BL21 (DE3)-plysS.
