Hansman1,2 1Schaller Research Group, University of Heidelberg and the German Cancer Research Center, 2Department of Infectious Diseases, Virology, University of Heidelberg Here, we describe a method to express and purify high quality norovirus protruding (P) domains in E. coli for use in X-ray crystallography studies. This method can be applied to other calicivirus P domains, as well as non-structural proteins, i.e., viral protein genome-linked (VPg), protease, and RNA dependent RNA polymerase (RdRp).
