Wasp is an important venomous animal that can induce human fatalities. Aortic thrombosis and cerebral infarction are major clinical symptoms after massive wasp stings but the reason leading to the envenomation manifestation is still not known. In this paper, a toxin protein is purified and characterized by Sephadex G-75 gel filtration, CM-Sephadex C-25 cationic exchange and fast protein liquid chromatography...
Mastoparans are a family of small peptides identified from the venom of hymenopteroid insects. Although they have been characterized as early as 1979, and so far are recognized as a leading biomolecule in potential drug therapy, their precursors, mastoparanogen, have still not been determined. In this paper, several mastoparans from the venom of the wasp Vespa magnifica (Smith) are reported. The cDNA...
The hornet possesses highly toxic venom, which is rich in toxin, enzymes, and biologically active peptides. Several bradykinin-like peptides, vespakinins, have been found in wasp venoms since 1970s, but the mode of biosynthesis of these peptides is unknown. In the present study, a vespakinin M was purified from venom of Vespa magnifica. Its primary sequence was established as GRPPGFSPFRID. The cDNA...
The hornet possesses highly toxic venom, which is rich in toxin, enzymes and biologically active peptides. Many bioactive substances were identified from wasp venom. Two families of antimicrobial peptides were purified and characterized from the venom of the wasp, Vespa magnifica (Smith). The primary structures of these peptides are homologous to those of chemotactic peptides and mastoparans isolated...
