The Effect of Lanthanide and Transition Metal Ions on the Fluorescence Spectra for the Anticoagulation Factor of Snake Venom

摘要

The effect of lanthanide and transition metal ions on the fluorescence spectra of theanticoagulation factor(ACF)of snake venom has been studied.It is postulated that the quenching oftryptophan residue fluorescence by lanthanide and transition metal ions is caused by the metal ion-inducedconformation change of ACF.
