A survey of plasmids for 51 prion protein constructs from bank vole, cat, cattle, chicken, dog, elk, ferret, frog, fugu, horse, human, pig, sheep, turtle, and wallaby, and for 113 mouse prion protein constructs and variants thereof, is presented. This includes information on the biochemistry of the recombinant proteins, in particular on successful and unsuccessful expres-sion attempts. | ỊFEBS Journal Prion protein library of recombinant constructs for structural biology Simone Hornemann Ị Barbara ChristenỊ Christine von Schroetter Daniel R.

This includes information on the biochemistry of the recombinant proteins in particular on successful and unsuccessful expression attempts. The plasmid library was generated during the past 12 years in the context of NMR structure determination and biophysical characterization of prion proteins in our laboratory. The plasmids are now available for general use and are distributed free of charge to not-for-profit institutions. Received 23 December 2008 revised 12 February 2009 accepted 13 February 2009 doi 10.1111 j.1742-4658.2009.06968.x Expression of the prion protein PrP in its cellular form PrPC in healthy organisms is intimately related to susceptibility to transmissible spongiform encephalopathies such as scrapie in sheep bovine spongiform encephalopathy chronic wasting disease in deer and Creutzfeldt-Jakob disease in humans 1 . Transmissible spongiform encephalopathies are related to the conversion of PrPC to a protease-resistant b-sheet-rich scrapie form 2 .
