一般描述

Chemical structure: peptide

应用

Magainin I has been used in DNA binding assay.[1] It has also been used to study its antimicrobial susceptibility.[2]

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

生化/生理作用

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,[3] and is naturally found on the skin of African clawed frog. It has a broad spectrum specificity towards many gram-negative bacteria.[4] It has the ability to make transmembrane pores on the bacterial cell membrane, which leads to cell lysis.[3] It is considered nontoxic to mammalian cells.[2]
