1CR9, 1CU4 - PubMed Abstract: 
The X-ray crystallographic structures of the anti-Syrian hamster prion protein (SHaPrP) monoclonal Fab 3F4 alone, as well as the complex with its cognate peptide epitope (SHaPrP 104-113), have been determined to atomic resolution. The conformation of the decapeptide is an Omega-loop ...
