Abstract

Intact PrPc and selected constructs will be produced in large amounts using bacterial expression. The recombinant protein will be used for spectroscopic and biophysical experiments to probe the molecule's folding, stability and structure in solution and where relevant, its conversion to the PrPsc form. Mutations will be introduced on PrPc and constructs, such as the 121-231, to modify the stability of the tertiary structure. The mutated material, and the information it provides, will be used in folding and crystallisation experiments, in the PrPc to PrPsc conversion studies at IAH and to support the transgenic programme. The crystallisation programme will include experiments with the 121- 231 construct and similar constructs trimmed of mobile segments, investigations on other constructs and mutated constructs and the N-terminal octapeptide repeat. There will be co- crystallisation studies with a range of ligands, concentrating on monoclonal Fab's and metal ions. The research will be carried out jointly with the IAH and will be co- ordinated with the recently initiated programme to study the behaviour and structure of the mammalian produced intact PrPc.
