Light-driven ion-translocating rhodopsins in marine bacteria

Highlights • Marine bacteria contain three different rhodopsins that pump H+ , Na+ and Cl−. • Spectroscopic studies revealed active transport mechanisms of marine bacterial rhodopsins. • KR2 is a compatible Na+ –H+ pump, whose function depends on the environment. • Na+ binding in the dark is not nee...

Zusammenfassung:	Highlights • Marine bacteria contain three different rhodopsins that pump H+ , Na+ and Cl−. • Spectroscopic studies revealed active transport mechanisms of marine bacterial rhodopsins. • KR2 is a compatible Na+ –H+ pump, whose function depends on the environment. • Na+ binding in the dark is not needed for transport and Na+ is taken up upon formation of O intermediate.
