title: Purification and partial biochemical characterization of an edema inducing phospholipase A2 from Vipera russelli (Russell's viper) snake venom.
abstract: A phospholipase A2 (VRV PL-VI) from Vipera russelli venom was purified to homogeneity in a single step on CM-Sephadex C-25 column. VRV PL-VI is a basic protein with a mol. wt of about 12,000 and showed a basic pH optimum and a high temperature maximum. It hydrolysed purified phospholipids in the order of phosphatidylethanolamine greater than phosphatidylcholine much greater than phosphatidylserine greater than phosphatidylinositol = 0. It is toxic with an LD50 value (i.p.) of 3.5 micrograms/g body weight in mice and it induced persistent edema in the mouse foot pad.
