A strategy for the accurate determination of protein solution structures starting from X-ray data and a minimal set of NMR data is proposed and successfully applied to two complexes of calmodulin (CaM) with target peptides not previously described. Its implementation in the present case is based on the use of lanthanide ions as substitutes for calcium in one of the four calcium binding sites of CaM and the collection of pseudocontact shift (pcs) and residual dipolar coupling (rdc) restraints induced by the paramagnetic metals ...
