Antimicrobial peptide that is rapidly bactericidal against Gram-positive bacteria (MIC=12.5 ug/ml against S.aureus, and MIC=100 ug/ml against M.luteus). Is also active against clinical antibiotics-resistant bacterial strains. Forms a helical membrane channel in the prey. Expressed by the venom gland. Is highly capable of inhibiting antibiotic-resistant pathogen growth, including methicillin-resistant S.aureus. In vivo, shows high antimicrobial activity on a S.aureus-infected mouse model (PubMed:19854232). Belongs to the non-disulfide-bridged peptide (NDBP) superfamily. Short antimicrobial peptide (group 4) family.
