Mapping the reverse cross-saturation effect on the structure. (A) Mapping the methyl Chemical Shift Perturbation (CSP) on the structure of Ca²⁺-CIB1 in complex with αIIb; the methyl CSP values were previously reported;¹⁷ (B) mapping the signal loss values from reverse cross-saturation experiments on the structure of Ca²⁺-CIB1 in complex with αIIb. In both panels, the dotted lines (red) resemble possible orientations of αIIb-L in its complex structure with Ca²⁺-CIB1.
