Rotational diffusion tensor of CD and CSD within full-length hHP1β.

Diffusion tensor parameters for the different tumbling models, obtained from experimental 15N spin-relaxation data through ROTDIF, are listed: the overall rotational correlation time τc; Dxx, Dyy and Dzz are the principal values of the diffusion tensor; Q is the quality factor defined as in [27]; P defines the probability that an improvement in the fit when a more complex model is applied has occurred by chance. The best model for CD and CSD is marked in bold. The little improvement in the fit with the more complex fully-anisotropic model was not statistically significant for CD.
