چکیده

The photocycle of the acid-purple form of bacteriorhodopsin (BR) was studied by multiwavelength absorption kinetic measurements. The data were evaluated using a new method based on the differences in the kinetics of the absorption changes at different wavelengths [Tokaji, Zs. (1995) FEBS Lett. 357, 156-160]. The evaluation indicates that, in contrast to the previous suggestion, the photocycle of the acid purple BR contains an intermediate that, in its spectral and kinetic properties, resembles the N intermediate of the alkaline BR photocycle.

FTIR spectroscopy of bacteriorhodopsin microcrystals at Beamline 1.4

Bacteriorhodopsin (bR) is the sole protein component of the purple membrane of Halobacterium salinarium . The function of bR in vivo is to convert solar energy into a pH gradient across the cell membrane which the organism uses to drive ATP synthesis . Bacteriorhodopsin undergoes a light-induced cycle of physicochemical changes for for every proton it pumps out of the cell. The photocycle of bR...

The decay rate of the Bacteriorhodopsin (BR) photocycle intermediate M412 and proton, the proton pump efficiency (H+/M412), the ratios of M412 to other intermediates and the rotational correlation time (tauc) in purple membrane (PM) fragments treated by the zwitterionic detergent 3-[(3-cholamidopropyl)-dimethylammonio]-1-propanesulfonate (CHAPS) with different concentrations were studied. The r...

Effect of genetic modification of tyrosine-185 on the proton pump and the blue-to-purple transition in bacteriorhodopsin.

The retinylidene chromophore mutant (Y185F) of bacteriorhodopsin, in which Tyr-185 is substituted by phenylalanine, is examined and compared with wild-type bacteriorhodopsin expressed in Escherichia coli; both were reinstituted similarly in vesicles. The Y185F mutant shows (at least) two distinct spectra at neutral pH. Upon light absorption, the blue species (which absorbs in the red) behaves a...

Crystal structure of the D85S mutant of bacteriorhodopsin: model of an O-like photocycle intermediate.

Crystal structures are reported for the D85S and D85S/F219L mutants of the light-driven proton/hydroxyl-pump bacteriorhodopsin. These mutants crystallize in the orthorhombic C222(1) spacegroup, and provide the first demonstration that monoolein-based cubic lipid phase crystallization can support the growth of well-diffracting crystals in non-hexagonal spacegroups. Both structures exhibit simila...

The function of bacteriorhodopsin in Halobacterium salinarum is to pump protons from the internal side of the plasma membrane to the external after light excitation, thereby building up electrochemical energy. This energy is transduced into biological energy forms. This review deals with one of the methods elaborated for recording the charge transfer inside the protein. In this method the curre...
