一般描述

Chemical structure: peptide

Gramicidin A is a linear pentadecapeptide antibiotic produced by Bacillus brevis.[1] The transmembrane protein contains a left-handed helix with alternating L and D residues.[2]

应用

Gramicidin A is used for studies on bacterial cell wall permeabilization and monovalent cation channel formation. Gramicidin has also been shown to inhibit transcription of T7 phage DNA, inhibit membrane-bound epidennal adenosine triphosphatase, suppress human lymphocyte blastogenesis in vitro and prolong heart allograft survival in the rat model [3] [4] [5]. It has also been used to study its role in phospholipids adsorption during air-water interface.[6]

生化/生理作用

Gramicidin A increases the permeability of bacterial cell membranes, which allows inorganic monovalent cations to travel through unrestricted. This destroys the ion gradient between the cytoplasm and the extracellular environment [7]. Gramicidin A acts as neutral carrier and helps in the establishment of ion flux across the lipid bilayer.[2]

Gramicidin A is a polypeptide antibiotic that forms single ion monovalent cation channels in biological membranes.
