一般描述

Chemical structure: peptide
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.

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 . It has also been used to study its role in phospholipids adsorption during air-water interface.

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 . Gramicidin A acts as neutral carrier and helps in the establishment of ion flux across the lipid bilayer.
Gramicidin A is a polypeptide antibiotic that forms single ion monovalent cation channels in biological membranes.

Linear polypeptide antibiotic gramicidin is known to interact with the cell membrane and deregulate cation exchange. Because perturbation of cell membrane function may suppress the immune cell network, the authors investigated the effects of gramicidin on lymphocyte blastogenesis in vitro

Gramicidin, a peptide antibiotic produced by Bacillus brevis, inhibits initiation of transcription by RNA polymerase (nucleosidetriphosphate:RNA nucleotidyltransferase, EC 2.7.7.6). We show here that the presence of gramicidin causes an increase in the rate of cleavage of the sigma subunit of
