[Isolation and purification of two lipolytic enzymes from Vespa orientalis venom]

Two lipolytic enzymes--phospholipase A2 and lysophospholipase A1 were isolated in individual state from the venom of the big hornet Vespa orientalis. It was shown that these enzymes have approximately the same molecular weight of about 26 000, but differ in their electrophoretic mobilities. Besides, the enzymes possess marked specificity to lecithin and L-lysolecithin, respectively.
