The venom peptides from the scorpion Heterometrus spinifer have been poorly characterized so far. Here, we identified a novel class of antimicrobial peptides from the venom gland of H. spinifer, which were referred to as HsAp, HsAp2, HsAp3 and HsAp4, respectively. Each of the four peptides consists of 29 amino acid residues, and is cationic and weakly amphipathic. They display no significant homology...
The sting of the black scorpion Heterometrus spinifer, which can cause intense localized pain, has not been reported to produce lethal cardiovascular complications, which are well known to result from scorpion envenomation as a consequence of a massive release of catecholamines. Therefore, we have undertaken a biochemical and pharmacological characterization of the venom of H. spinifer. Pharmacologically,...
