psacotheasin is a 34 amino acid knottin-type antimicrobial peptide (CIAKGNGCQPSGVQGNCCSGHCHKEPGWVAGYCK) from the yellow-spotted long-horned beetle Psacothea hilaris (Hwang et al, 2010). Chemically synthesized psacotheasin shows potent activities against both Gram-positive bacteria and Gram-negative bacterial strains. Psacotheasin shows remarkable antifungal properties without hemolytic activity against human erythrocytes. It acts as a pore-forming peptide that depolarizes and perturbs the plasma membrane (Hwang et al, 2010).
