Application

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. It has also been used as an analyte for the purpose of infrared laser desorption or ionization from silicon.

Biochem/physiol Actions

Linear polypeptide antibiotic mixture of gramicidin A, B, C, and D.
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.
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.

General description

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.

The cellular resting membrane potential (Vm) not only determines electrical responsiveness of excitable cells but also plays pivotal roles in non-excitable cells, mediating membrane transport, cell-cycle progression, and tumorigenesis. Studying these processes requires estimation of Vm, ideally over long periods
