Calmodulin exhibits high affinity, calcium-dependent binding of the mastoparans—a group of cytoactive tetradecapeptides. The dissociation constants for the peptide-calmodulin complexes determined in 0.20 N KCl, 1.0 mM CaCl 2, pH 7.3 are∼ 0.3 nM for mastoparan,∼ 0.9 nM for mastoparan X, and∼ 3.5 nM for Polistes mastoparan. The dissociation constant for the mastoparan-calmodulin complex is the smallest known for any calmodulin binding protein or peptide, suggesting that some type of peptide-calmodulin interaction could be physiologically significant.
