| The present study reports the characterization of Ls-Stylicin1, a novel antimicrobial peptide from the penaeid shrimp, Litopenoeus stylirostris. The predicted mature peptide of 82 residues is negatively charged (theoretical pl=5.0) and characterized by a proline-rich N-terminal region and a C-terminal region containing 13 cysteine residues. The recombinant Ls-Stylicin1 has been isolated in both monomeric and dimeric forms. Both display strong antifungal activity against Fusarium oxysporum (1.25 mu M < MIC <2.5 mu M), a pathogenic fungus of shrimp, but lower antimicrobial activity against Gram () bacteria, Vibrio sp. (40 mu M < MIC <80 mu M). However, rLs-Stylicin1 is able to agglutinate Vibrio pennaeicidae in vitro in agreement with its potent... |
