Figure 1. Primary structure of the human prion protein. The mature human prion protein consists of residues 23–230. The amino acid sequence of the OPR region from residues 51 to 91 (gray boxes) is shown at the bottom, where residues unambiguously assigned in the NMR spectra are underlined. For the segment 54–89 only a single set of resonance signals was detected for each repeated amino acid (see the text). Regular secondary structure elements are represented in black. The disulfide bond (S–S) between Cys179 and Cys214 is drawn as a gray line. Arrows at the top indicate N-terminal truncations sites of the hPrP constructs used in this study.
