Description

Amino Acid Sequence

Gly-Ile-Gly-Lys-Phe-Leu-His-Ser-Ala-Gly-Lys-Phe-Gly-Lys-Ala-Phe-Val-Gly-Glu-Ile-Met-Lys-Ser

Application

Initial sites of magainin I binding to E. coli have been shown to be lipopolysaccharide.

Magainin I has been used in DNA binding assay. It has also been used to study its antimicrobial susceptibility.

Other Notes

Lyophilized from 0.1% TFA in H2O

Biochem/physiol Actions

Antibiotic peptide. Thought to preferentially bind to anionic phospholipids abundant in bacterial membranes with the formation of dynamic peptide-lipid supramolecular pore and cell permeabilization, magainins are positively charged and amphiphatic. Binding to artificial neutral membranes has also been demonstrated.

Magainin is a 23-residue peptide, and is naturally found on the skin of African clawed frog. It has a broad spectrum specificity towards many gram-negative bacteria. It has the ability to make transmembrane pores on the bacterial cell membrane, which leads to cell lysis. It is considered nontoxic to mammalian cells.
