Ab. Druzhko et Sk. Chamorovsky, THE CYCLE OF PHOTOCHROMIC REACTIONS OF A BACTERIORHODOPSIN ANALOG WITH 4-KETO-RETINAL, Biosystems, 35(2-3), 1995, pp. 133-136
Photochemical reactions in a bacteriorhodopsin analog with 4-keto-reti
nal (4-keto-BR) were studied by using low-temperature and pulsed laser
absorption spectroscopy. A photocycle of the photochemical reactions
of 4-keto-BR is proposed, which, unlike the photocycle of native BR, i
ncludes several spectrally and kinetically distinguishable M-type and
O-type intermediates.
