Ein Ionophor ist ein Molekül, das Ionen durch eine Membran transportiert. Einige Bakterien bilden Ionophore, also Moleküle, die die Permeabilität von Membranen für Ionen erhöhen. Oft haben solche Moleküle eine antibiotische Wirkung, da sie Ionenkonzentrationsgefälle abbauen. Manche Ionophore werden von Bakterien als porenbildendes Toxin verwendet. Man unterscheidet Carrier-Ionophore und kanalbildende Ionophore: Web1 jan. 1988 · INTRODUCTION Ion carriers as a class of ionophores are lipophilic complexing agents having the capability of binding ions reversibly and to transport them across organic membranes by carrier translocation (refs. 1, 2). Ideally, selective ion carriers render a membrane permeable for one given sort of ion I only.
