We have isolated a novel defensin from the mucus of the wood wasp Xiphydria camelus. The Edman degradation in 50 cycles revealed a peptide sequence similar to other insect defensins. The complete 55 amino acid residues sequence of X. camelus defensin was proposed based on the mass spectrometry analysis and by the deduction based on the comparison with the sequences of other hymenopteran defensins. The defensin was tested against both Gram-positive and -negative bacteria.
