Abstract: | The effects of Mg-ATP, EGTA, EDTA and dicyclohexylcarbodiimide on the changes in the intensity of light scattering were studied in rat brain synaptic vesicles (SV) suspended in saccharose-buffer medium. Specific interactions between SV and isolated synaptic junctional complex were observed in the presence of Mg-ATP and calmodulin. An in vitro model of exocytosis is discussed. |
