measure and best-fit couplings, where all couplings have been
normalized relative to 1D[NH]. No couplings were measured for
Asn 42 because residue 43 is a Pro and Asn 42 HN is broadened by
rapid solvent exchange at pH 7.0. Residues Met 76 -Asp 81 are
highly flexible and excluded from the structure calculation. The
symbols correspond to apo CaM (square), parvalbumin (triangle)
and Ca^2+ -CaM (circle) starting structures.
