Ion-stripped bovine brain calmodulin (CaM) binds 4 moles Cd2+ as well as 4 moles Ca2+ per mole protein, with similar affinity; in the presence of 1 mM Mg2+ the molar binding ratio of CaM for Ca2+ decreased to 3, the apparent K0.5 for Ca2+ nearly doubled, but the binding characteristics of CaM for Cd
