Information on the temporal order, the kinetics, and the energetics of each of the reaction intermediates is required in order to fully elucidate the mechanism of catalytic interaction of G proteins with their receptors. Intrinsic monitors, such as light s ...
Complex visual hallucinations are a well-known feature of electrical stimulation or epileptic discharge in the temporal lobe. It has been proposed that these visual hallucinations result from an electrical interference with the ventral visual processing st ...
Absorption, fluorescence and excitation spectra of three-dimensional bacteriorhodopsin crystals harvested from a lipidic cubic phase are presented. The combination of the spectroscopic expts. performed at room temp., controlled pH and full external hydrati ...
We present mol. dynamics simulations of bovine rhodopsin in a membrane mimetic environment based on the recently refined x-ray structure of the pigment. The interactions between the protonated Schiff base and the protein moiety are explored both with the c ...
Assuming that the photoreceptor response of the human visual system is adaptive and non-linear, we can derive mathematical properties that can account for both color discrimination and chromatic adaptation. This could be due to the photoreceptors’ response ...
Two methods for the estn. of the current bypass in solid state electrochem. are presented. The current bypass was estd. from the current-voltage curves of a tubular cell with one bipolar element and from the current-voltage curves of a monolith with severa ...
Cyclisation reactions on pentapeptides containing the turn promoting residues Gly and Pro are investigated. Although the cyclisation reaction is fast, solvent-dependent mixtures of cyclic penta- and decapeptides are observed. NMR studies suggest a strong d ...
