Prospects for Octopus Rhodopsin Utilization in Optical and Quantum Computation
Visual membranes of octopus, whose main component is the light-sensitive signal transducer octopus rhodopsin (octR), are extremely highly ordered, easily capture single photons, and are sensitive to light polarization, which shows their high potential for use as a QC detector. However, artiˇcial membranes made of octR are neither highly enough ordered nor stable, while the bacterial homolog of ...
متن کاملMechanism of the Spermatophoric Reaction in the Giant Octopus of the North Pacific, Octopus Dofleini Martini
In the giant octopus of the North Pacific, Octopus dofleini martini, the male reproductive tract contains up to 10 spermatophores. Each is about a metre long. It has a tube-shaped body surrounded by a tough, thin membrane, the 'outer tunic'. The body consists of two parts. The thicker part, which during copulation emerges first from the 'penis', contains the sperm rope with IO-IO tightly packed...
متن کاملTime-resolved spectroscopy of ultrafast photoisomerization of octopus rhodopsin under photoexcitation.
A primary process in vision is the cis-trans photoisomerization of a chromophore of rhodopsin, called retinal. In the present work, we have performed ultrafast time-resolved spectroscopy of octopus rhodopsin using a sub-5-fs pulse laser. In comparison with our previous study on bacteriorhodopsin, we found that octopus rhodopsin follows similar dynamics after photoexcitation but with different t...
متن کاملReaction dynamics during the testing of polymerization catalyst
The olefins polymerization process in a slurry reactor is discussed. The reaction rate dynamics was analyzed and the contributions of feed flow, gas-liquid mass transfer, polymerization reaction, and catalyst deactivation were estimated. The propylene solubility in a solvent mixture “heptane” was calculated using Soave-Redlich-Kwong equation of state. These data were then approximated by Henry-...
متن کاملCrystallographic analysis of the primary photochemical reaction of squid rhodopsin.
Visual signal transduction is initiated by the photoisomerization of 11-cis retinal upon rhodopsin ligation. Unlike vertebrate rhodopsin, which interacts with Gt-type G-protein to stimulate the cyclic GMP signaling pathway, invertebrate rhodopsin interacts with Gq-type G-protein to stimulate a signaling pathway that is based on inositol 1,4,5-triphosphate. Since the inositol 1,4,5-triphosphate ...
