a 〈Sa〉 represents the 10 lowest-energy structures. For 〈Sa〉, each value represents the mean± S.D. with the number of restraints used to calculate these values shown in parentheses.
b R factor is defined as in XPLOR-NIH (28).
c R and r.m.s.d. of CαHα RDCs are scaled to NH.
d Average r.m.s.d. of the 10 lowest energy structures from the mean coordinates for structured residues 12–50, 72–83 and 94–148.
