Effect of Antimicrobial Peptide-Amide: Indolicidin on Biological Membranes
Indolicidin, a cationic antimicrobial tridecapeptide amide, is rich in proline and tryptophan residues. Its biological activity is intensively studied, but the details how indolicidin interacts with membranes are not fully understood yet. We report here an in situ atomic force microscopic study describing the effect of indolicidin on an artificial supported planar bilayer membrane of dipalmitoy...
متن کاملCation-pi interactions stabilize the structure of the antimicrobial peptide indolicidin near membranes: molecular dynamics simulations.
We implemented molecular dynamics simulations of the 13-residue antimicrobial peptide indolicidin (ILPWKWPWWPWRR-NH2) in dodecylphosphocholine (DPC) and sodium dodecyl sulfate (SDS) micelles. In DPC, a persistent cation-pi interaction between TRP11 and ARG13 defined the structure of the peptide near the interface. A transient cation-pi interaction was also observed between TRP4 and the choline ...
متن کاملEffect of Amino Acid Substitutions on Biological Activity of Antimicrobial Peptide: Design, Recombinant Production, and Biological Activity
Recently, antimicrobial peptides have been introduced as potent antibiotics with a wide rangeof antimicrobial activities. They have also exhibited other biological activities, including antiinflammatory,growth stimulating, and anti-cancer activities. In this study, an analog of MagaininII was designed and produced as a recombinant fusion protein. The designed sequence containe...

متن کاملMode of action of the antimicrobial peptide indolicidin.
Indolicidin is a cationic antimicrobial peptide isolated from bovine neutrophils. It consists of only 13 amino acids, has the highest tryptophan content of any known protein, and is amidated at the carboxyl terminus in nature. By circular dichroism spectroscopy a weak poly-L-proline II extended helix structure was observed that became substantially more pronounced upon interaction with liposome...
