The determination of binding constants of metal ions to biomolecules is approachable via many techniques. Metal ion NMR spectroscopy is an alternative to more traditional techniques and is complementary to them, particularly in investigations of the interactions of metal ions with relatively small peptides containing multiple ionizing groups. The method requires relatively small amounts of material, is fairly fast, and is carried out at equilibrium. Our study has been of calcium and magnesium ion binding to gamma-carboxyglutamic acid (Gla)-containing peptides. Dissociation constants of approximately 0.6 mM for the binding of either metal ion to Z-D-Gla-D-Gla-OMe have been obtained. The procedure for determination of these constants via metal ion NMR is discussed.
