Lucifensin, a novel insect defensin of medicinal maggots identified recently in our laboratory, is 40 amino acid residues and three intramolecular bridges peptide. Oxidative folding of linear lucifensin precursor prepared by solid phase peptide synthesis resulted in a peptide with a pattern of disulfide bridges identical to that of native lucifensin. Synthetic lucifensin was active against Gram-positive bacteria and was not hemolytic. The presence of disulfide bridges and the N-terminal part of its molecule for the structure and antimicrobial activity is essential.
