Figure 4

Plots of PBP 5 residue backbone N-H dynamic values. Error bars indicate standard deviations. (A) Plot of S2 from the Modelfree calculation for each residue. The lower the S2 value the greater amplitude of motion for the N–H vector. (B) Plot of effective correlation time (τe, ♦) and conformational exchange (Rex, ■) from the Modelfree calculation for each residue that is described by the parameter. Data are only presented if the motional model for the residues is contained in these terms. The parameter τe describes fast motions on the ps time scale and Rex describes conformational exchange on the ms time scale.
