Application: 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 . It has also been used to study its role in phospholipids adsorption during air-water interface.
Biochem/physiol Actions: 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 . Gramicidin A acts as neutral carrier and helps in the establishment of ion flux across the lipid bilayer.
Biochem/physiol Actions: Gramicidin A is a polypeptide antibiotic that forms single ion monovalent cation channels in biological membranes.
General description: Chemical structure: peptide
General description: Gramicidin A is a linear pentadecapeptide antibiotic produced by Bacillus brevis. The transmembrane protein contains a left-handed helix with alternating L and D residues.
Other Notes: Keep container tightly closed in a dry and well-ventilated place.Moisture sensitive. Store under inert gas. Keep in a dry place.
