Characterisation of antibacterial peptides from the venom of Cupiennius salei (Araneae: Ctenidae). Diplomarbeit am Zoologischen Institut der Universität Bern, 19 S.
The characterisation of the antimicrobial activity of six antibacterial peptides, isolated from the venom of the neotropical wandering spider Cupiennius salei is reported. The peptides have a molecular weight, determined by electrospray ionisation-mass spectrometry, between 3 to 4 kDa, and they consist of approximately 26 to 35 amino acids. All six peptides lack cysteines but they are rich in lysine. Peptide 1 is very closely related to CSTX-4, a known bactericidal and insecticidal toxin from the venom of Cupiennius salei
