Variation in backbone dihedral and side-chain torsion angles and comparisons with the crystal structure. (ac) Spread of the values for the backbone dihedral angles φ and ψ in the bundles of 20 conformers representing the NMR structure (a), the reference NMR structure (b) and the reference crystal structure (c) of NP_247299.1 (Fig. 2[link]) and comparisons with the crystal structure. In this presentation, the mean value in the bundles of 20 conformers is at 0°, the blue vertical bars represent the spread of the values within the bundles and the red dots indicate the deviation of the crystal structure values from the corresponding mean values for the bundle of 20 conformers. (df) Spread of the values for the amino-acid side-chain torsion angles χ1 and χ2 in the NMR structure (d), the reference NMR structure (e) and the reference crystal structure (f) of NP_247299.1 (Fig. 2[link]) and comparison with the crystal structure. At the top, the locations of the regular secondary structures are indicated and asterisks identify the residues with solvent accessibility below 15% in the NMR structure. Filled circles at the bottom of (f) indicate four residues for which the side chains were truncated in the crystal structure because they were not observed in the electron-density maps.
