Fig. 4.
A comparison of HRP dynamics in the free and substrate-bound states. (a) Tw-dependent eccentricities of the blue (circles) and red (squares) states of free HRP. (b) Eccentricities of HRP ligated with 2-NHA (filled squares), BHA (filled circles), BZA (open squares), BZH (open circles), and NMBZA (triangles). The solid lines are obtained by simultaneously fitting the linear and 2D-IR data to determine the FFCFs.
