Abstract excerpt
The photochemical and subsequent thermal reactions of phoborhodopsin (pR490), which mediates the negative phototaxis (phobic reaction) of Halobacterium halobium, were investigated by low-temperature spectrophotometry. At room temperature, the absorption spectrum of pR490 displayed vibrational structure with a maximum at 490 nm and a shoulder at 460 nm, which were remarkably sharpened by cooling, resulting in the...
