Figure 6.

Local diffusion times (D = 1/(6τ_m)) plotted versus Y₂⁰(θ), in which θ is the orientation of the methyl symmetry axis in the structure of RNase H oriented in the principal axis system of the diffusion tensor determined from ¹⁵N spin relaxation. The values of D for the 12 slowest tumbling residues (for which internal motions are well-separated from overall rotation) are shown in red and agree quantitatively with predictions from the overall rotational diffusion tensor determined from ¹⁵N relaxation data (red line), when adjusted for the sample temperature and D₂O viscosity.
