설명

일반 설명

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]

애플리케이션

Gramicidin from Bacillus aneurinolyticus (Bacillus brevis) has been used as a control to measure the rate of diffusion of protonated β-lactams through the lipid bilayer in liposome swelling assay.[3] It has also been used as an analyte for the purpose of infrared laser desorption or ionization from silicon.[4]

생화학적/생리학적 작용

Linear polypeptide antibiotic mixture of gramicidin A, B, C, and D. Gramicidin A acts as neutral carrier and helps in the establishment of ion flux across the lipid bilayer.[2]

Linear polypeptide antibiotic, a mixture of gramicidin A, B, C, and D. Gramicidin D, a channel-forming ionophore that flip-flops slowly across the membrane is a known Pgp substrate and surprisingly was found to inhibit Pgp ATPase activity. This inhibition was reversed by other Pgp substrates suggesting a common drug binding site among MDR substrate-type drugs and chemosensitizers.
