Description

Description générale

Naturally occurring, ion channel-forming pentadecapeptide antibiotic that renders membranes permeable to protons and alkali metal ions. Causes red blood cell lysis at concentrations of 0.5-1.0 µg/ml. Gramicidin A causes K⁺/H⁺ exchange in mitochondria in a non-voltage dependent manner.

Naturally-occurring ion channel-forming pentadecapeptide. The association of two gA peptides causes the formation of a monovalent cation-selective ion channel. Causes K⁺/H⁺ exchange in mitochondria in a non-voltage dependent manner. Causes red blood cell lysis at 0.5-1.0 µg/ml.
