Blancuzzi Y, Padilla A, Parello J, Cave ASymmetrical rearrangement of the cation-binding sites of parvalbumin upon Ca2+/Mg2+ exchange. A study by 1H 2D NMRBiochemistry v32, p.1302-1309Two forms of parvalbumin, i.e., the fully Ca-loaded form PaCa2 and the fully Mg-loaded form PaMg2, are investigated by 2D 1H NMR in solution. A detailed analysis of the resonances, which belong to residues involved in direct coordination of Ca2+ and Mg2+, establishes that the sixth ligand, a highly conserved Glu residue at the relative position 12 in both cation-binding sites CD and EF, undergoes a conformational rearrangement through a 120 degrees rotation of its side chain about the C alpha-C beta bond with PaMg2 adopting the less energetically favored g- conformation, as inferred from scalar coupling constants and dipole-dipole contacts measured on the COSY and NOESY spectra, respectively....
