First, halorhodopsin is capable of pumping protons after illumination with green and blue light in the same direction as chloride. Second, mutated bacteriorhodopsin where the proton acceptor Asp85 and the proton donor Asp96 are replaced by Asn showed proton pump activity after illumination with blue light in the same direction as wildtype after green light… CONTINUE READING
