| Abstract: | The own fluorescence of phospholipase A2 and orientotoxin at interaction of these components from Oriental hornet venom with calcium, strontium, lantan, magnesium ions has been investigated. Ca2+, La3+, Sr2+--activators of phospholipase activity--increase the quantum output of fluorescence. In the presence of Ca2+ the temperature of semitransitional process of thermoinactivation of investigated polypeptides increases by 2 degrees C. |
