Cecropin B is a 37-residue cationic antimicrobial peptide derived from the haemolymph of Bombyx mori. The precise mechanism by which cecropins exert their antimicrobial and cytolytic activities is not well understood. Crystals of cecropin B were obtained by the hanging-drop vapour-diffusion method using polyethylene glycol as a precipitant at 289 K. The crystal diffracted to 1.43 Å resolution using X-ray radiation and belonged to the orthorhombic space group P1, with unit-cell parameters a = 15.08, b = 22.75, c = 30.20 Å, α = 96.9, β = 103.1, γ = 96.5°. The asymmetric unit contained only one molecule of cecropin B, with a calculated Matthews coefficient of 2.48 Å3 Da−1 and a solvent content of 50.4%. [ABSTRACT FROM AUTHOR] |
