==Solution structure of arenicin-1==
-
The solution structure and the mode of action of arenicin isoform 1, an, antimicrobial peptide with a unique 18-residue loop structure, from the, lugworm Arenicola marina were elucidated here. Arenicin folds into a, two-stranded antiparallel beta-sheet. It exhibits high antibacterial, activity at 37 and 4 degrees C against Gram-negative bacteria, including, polymyxin B-resistant Proteus mirabilis. Bacterial killing occurs within, minutes and is accompanied by membrane permeabilization, membrane, detachment and release of cytoplasm. Interaction of arenicin with, reconstituted membranes that mimic the lipopolysaccharide-containing outer, membrane or the phospholipid-containing plasma membrane of Gram-negative, bacteria exhibited no pronounced lipid specificity. Arenicin-induced, current fluctuations in planar lipid bilayers correspond to the formation, of short-lived heterogeneously structured lesions. Our results strongly, suggest that membrane interaction plays a pivotal role in the, antibacterial activity of arenicin.
