Figure 3.

Correlation plots comparing methyl-axis dynamics parameters derived from ¹³C relaxation measurements of the (L₅ + L₆) magnetization mode (I = 1/2 manifold) in ¹³CH₃ methyls using the scheme in Figure 2 (x-axes) with those derived from ¹³C relaxation in ¹³CHD₂ methyls (y-axes) for ILV-labeled samples of ubiquitin at 25 °C (upper row; (A) $S_{\text{axis}}^2$ and (B) τ_f; 29 correlations) and 5 °C (lower row; (C) $S_{\text{axis}}^2$ and (D) τ_f; 30 correlations). All data were collected at 600 MHz. The data for the L50δ2 and L56δ2 methyl sites were excluded from the plots because of large exchange contributions to their R₂ values. Linear correlation coefficients are shown at the top of each plot. Dashed lines are drawn at y = x.
