  8. Abstract : the effects of terbium ion on the conformation of calmodulin and on the interaction between calmodulin and melittin have been studied by the endogenous fluorescent spectrometry of calmodulin and melittin, and the sensitized fluorescent spectrometry of terbium ion, respectively. the results show that terbium ions have a tight binding site in the i and ii metal - binding sites of calmodulin. the conformation of calmodulin induced by terbium ion can bind melittin and transfer the tryptophane residue of melittin to a relatively hydrophobic environment, while the binding of melittin to calmodulin produces effect on the binding orders of terbium ion in camodulin. results from ft - ir spectrometry have revealed that upon binding of lanthanum ion, apo - calmodulin undergoes a conformational change with the increase of - helix content and the decrease of - sheet content. melittin ' s binding to calmodulin has no effect on its conformation induced by the binding of lanthanum ion to calmodulin
