Different levels of agreement are also observed in distributions of χ2, when χ1 is in its dominant rotameric state. Whereas the MFA rotameric predictions for I36, I44, I61, and L67 reproduce the distribution of rotamers for χ2 of the ensembles, I3 adopts more frequent occurrences in the g+/g− positions than in the ensembles (38%/14% compared to <6%/0%, respectively). This distribution for I3 χ2 is imposed by the very high anisotropy value for Cδ1(ηrdc = 0.7), not observed for other residues.
