title: 13C and 15N chemical shift assignments and secondary structure of the B3 immunoglobulin-binding domain of streptococcal protein G by magic-angle spinning solid-state NMR spectroscopy.
abstract: Complete 13C and 15N assignments of the B3 IgG-binding domain of protein G (GB3) in the microcrystalline solid phase, obtained using 2D and 3D MAS NMR, are presented. The chemical shifts are used to predict the protein backbone conformation and compared with solution-state shifts.
