¹⁵N relaxation dispersion of SSB-2 (12–224) measured at CPMG field strengths ranging from 20 to 1000 sec⁻¹. (A) R ₂ ^app as a function of the CPMG field strengths for residues Tyr20, Phe23, Ala149, Gly155, and Val169. (B) Distribution of R ₂ ^app values as measured at CPMG field strengths ranging from 20 to 1000 sec⁻¹ versus SSB-2 residue number (○) with the solid line connecting consecutive residues through their averaged values (•) of R₂ ^app. Values of ΔR ₂ ^app = R ₂ ^app (20 sec⁻¹) − R ₂ ^app (1000 sec⁻¹) are shown as the bar chart.
