| Abstract: | Sequence-specific resonance assignments of human beta 2-microglobulin (M(r) 12,000) and its secondary structure are determined by 2D NMR techniques. The protein is found to contain two antiparallel beta-sheets each of four beta-strands with the beta-sheets being connected by a single disulfide linkage. No evidence for any regular helical structure is found. Amide proton-solvent-exchange rate constants and 3JHN alpha coupling constants are evaluated. |
