Antibacterial peptide. Acts on the Mycobacterium abscessus subsp. massiliense cell wall. Reduces 40-50% of the bacterial load in macrophages infected with different M.abscessus strains. Is not cytotoxic towards mammalian cells, and shows no hemolytic activity against human erythrocytes. In vivo, reduces the bacterial load in the lungs, spleen, and liver of highly susceptible mice intravenously infected with M.abscessus. Expressed by the venom gland.
