Mode of Action of the Antibacterial Cecropin B2: A Spectrofluorometric Study

Abstract excerpt

Cecropin B2 (CecB) is a 35 amino acid residue, antibacterial peptide that was isolated from the hemolymph and cuticular matrix of the silkworm, Bombyx mori. Synthetic peptides with sequences corresponding to CecB and its truncated analogue, [3-->35]CecB, were synthesized and selectively labeled at their N-terminal amino acids with either 7-nitrobenz-2-oxa-1,3-diazol-4-yl (NBD) or rhodamine fluorescent probes....
