Boryeu Mao, Rajni Govindjee, Thomas G. Ebrey,* Maria Arnaboldi, Valeria Balogh-Nair, Koji Nakanishi,* and Rosalie Crouch* abstract: 5, 6-Dihydroretinal and 5, 6-dihydro-1, 1, 5, 9, 13-desmethylretinal are synthesized, and their all-trans isomers are shown toform pigment analogues (Xmax at 475 and 460 nm, respectively) of bacteriorhodopsin (purple membrane protein). The shift of the absorption maximum of the pigment from that of the protonated Schiff base of the chromophore for 5, 6-dihydrobacteriorhodopsin is small compared to that of the native pigment, suggesting that negativecharges similar to those controlling the of visual pigment rhodopsin exist near the cyclohexyl ring. Both pigment analogues undergo reversible light-induced spectral shifts reflecting cyclic pho-toreactions of the pigments. These results indicate that the absence of the C-5-C-6 double bond and of the five methyl groups of retinal does not abolish the photochemistry of these
