Oriented adsorption of purple membrane to cationic surfaces
We have investigated the orientation of isolated fragments of Halobacterium halobium purple membrane (PM) adsorbed to poly-L-lysine-treated glass (PL-glass), by quanitative electron microscopy. Three lines of evidence support the conclusion that the cytoplasmic side of the membrane is preferentially absorbed. First, monolayer freeze-fracture reveals nonrandom orientation; more fracture faces (8...
متن کاملCyclic-GMP enhances light-induced excitation and induces membrane currents in Drosophila retinal photoreceptors.
Phototransduction in the Drosophila retina appears to require the phosphoinositide signaling cascade following receptor/G-protein activation. Subsequent opening of membrane cationic channels causes excitation. The biochemical events underlying channel opening and regulation of sensitivity remain largely unknown. Evidence is mounting that phototransduction in Drosophila and other invertebrate sp...
متن کاملStudies of an acid-induced species of purple membrane from Halobacterium halobium.
A new spectral species of the purple membrane of Halobacterium halobium has been observed below pH 3.2. The formation of this new species is temperature-dependent and is favoured by increasing temperature up to the physiological range of the organism. The rate of formation at pH 3.0 and 22 degrees C is 7.9 x 10-3s-1. The spectral distribution and temperature-dependence of the new species sugges...

متن کاملCircular Dichroism of Light-harvesting Complexes from Purple Photosynthetic Bacteria*
The CD spectra of a range of antenna complexes from several different species of purple photosynthetic bacteria were recorded in the wavelength range of 190 to 930 nm. Analysis of the far UV CD (190 to 250 nm) showed that in each case except for the B800-850 from Chr. vinosum the secondary structure of the light-harvesting complexes contains a large amount of a-helix ( 2 5 0 % ) and very little...
