Protein-phospholipid-cholesterol interaction in the photolysis of invertebrate rhodopsin.
Three aspects of protein-phospholipid-cholesterol interaction in microvillar membranes of octopus photoreceptor cells were studied: (1) the effect of hydrophobic environment on the kinetics of thermal transformation in the photolysis of rhodopsin; (2) effects of cholesterol in microvillar membranes on protein-lipid interaction; (3) the effect of membrane proteins on the dynamic properties of li...
متن کاملChanges in Electrical Conductance of Rhodopsin on Photolysis
The change in electrical conductance of rhodopsin solutions was studied with flash-photolysis techniques. The whole pattern of the conductance change on illumination consists of three different processes: (I) the initial decrease, (II) the increase, and (III) the slow decrease, which are in decreasing order of reaction rate. The processes I, II, and III can be most distinctly recognized on flas...
متن کاملPhotolysis of iron-siderophore chelates promotes bacterial-algal mutualism.
Marine microalgae support world fisheries production and influence climate through various mechanisms. They are also responsible for harmful blooms that adversely impact coastal ecosystems and economies. Optimal growth and survival of many bloom-forming microalgae, including climatically important dinoflagellates and coccolithophores, requires the close association of specific bacterial species...
متن کاملChromophore structural changes in rhodopsin from nanoseconds to microseconds following pigment photolysis.
Rhodopsin is a prototypical G protein-coupled receptor that is activated by photoisomerization of its 11-cis-retinal chromophore. Mutant forms of rhodopsin were prepared in which the carboxylic acid counterion was moved relative to the positively charged chromophore Schiff base. Nanosecond time-resolved laser photolysis measurements of wild-type recombinant rhodopsin and two mutant pigments the...
متن کاملMethyl-accepting protein associated with bacterial sensory rhodopsin I.
In vivo radiolabeling of Halobacterium halobium phototaxis mutants and revertants with L-[methyl-3H] methionine implicated seven methyl-accepting protein bands with apparent molecular masses from 65 to 150 kilodaltons (kDa) in adaptation of the organism to chemo and photo stimuli, and one of these (94 kDa) was specifically implicated in phototaxis. The lability of the radiolabeled bands to mild...
