Xanthorhodopsin (xR) is a dual-chromophore proton-pump photosynthetic protein comprising one retinal Schiff base and one light-harvesting antenna salinixanthin (SX). The excitation wavelength-dependent transient population of the intermediate M demonstrates that the excitation of the retinal at 570 nm leads to the highest photocycle activity and the excitations of SX at 460 and 430 nm reduce the activity to
