Two processes lead to a stable all-trans and 13-cis isomer equilibrium in dark-adapted bacteriorhodopsin; effect of high pressure on bacteriorhodopsin, bacteriorhodopsin mutant D96N and fluoro-bacteriorhodopsin analogues.

Abstract excerpt

The combination of absorption spectroscopy and extraction techniques was applied to study the effect of high pressure on the dark-adapted state of bacteriorhodopsin, 14-(12-,10-)fluoro-bacteriorhodopsin, a D96N bacteriorhodopsin mutant, and 14-(12-,10-)fluoro-D96N. Evidence is presented that, at high pressure, the isomers' equilibrium is shifted from all- trans isomers towards the 13-cis isomers. Two groups of...
