  • Agroinfiltration contributes to VP1 recombinant protein degradation 
    Pillay, Priyen; Kunert, Karl J.; Van Wyk, Stefan George; Makgopa, Matome Eugene; Cullis, C.A. (Christoper Ashley); Vorster, Barend Juan (Routledge, 2016-08)
    There is a growing interest in applying tobacco agroinfiltration for recombinant protein production in a plant based system. However, in such a system, the action of proteases might compromise recombinant protein ...
  • Cysteine protease and cystatin expression and activity during soybean nodule development and senescence 
    Van Wyk, Stefan George; Du Plessis, Magdeleen; Cullis, C.A. (Christoper Ashley); Kunert, Karl J.; Vorster, Barend Juan (BioMed Central, 2014)
    BACKGROUND : Nodules play an important role in fixing atmospheric nitrogen for soybean growth. Premature senescence of nodules can negatively impact on nitrogen availability for plant growth and, as such, we need a better ...
  • Potential use of phytocystatins in crop improvement, with a particular focus on legumes 
    Kunert, Karl J.; Van Wyk, Stefan George; Cullis, C.A. (Christoper Ashley); Vorster, Barend Juan; Foyer, Christine H. (Oxford University Press, 2015-06)
    Phytocystatins are a well-characterized class of naturally-occurring protease inhibitors that function by preventing the catalysis of papain-like cysteine proteases. The action of cystatins in biotic stress resistance ...
  • Review : The future of cystatin engineering 
    Van Wyk, Stefan George; Kunert, Karl J.; Cullis, C.A. (Christoper Ashley); Pillay, Priyen; Makgopa, Matome Eugene; Schluter, Urte; Vorster, Barend Juan (Elsevier, 2016-05)
    Plant cystatins are naturally occurring protease inhibitors that prevent proteolysis by papain-like cysteine proteases. Their protective action against environmental stresses has been relatively well characterised. Still, ...
