While we do not probe directly the motion around the Cα–Cβ torsional angle from methyl group RDCs, this angle is still reflected in both of the δ-methyl groups. From the minimum search, we find that, in L8 where all three χ1 rotamers are present, χ2 prefers being in the g+ and g− positions when χ1 is in g+ (populations: 0.54 and 0.44) or tr (populations: 0.41 and 0.57), but prefers being in tr when χ1 is in g− (population: 0.66). Similarly in L67, three different distributions of tr, g+ and g− rotamers of χ2 are observed depending on the state of χ1.","tracks":[]}
