Modeling of phytochrome absorption spectra
Phytochromes constitute one of the six well-characterized families of photosensory proteins in Nature. From the viewpoint of computational modeling, however, phytochromes have been the subject of much fewer studies than most other families of photosensory proteins, which is likely a consequence of relevant high-resolution structural data becoming available only in recent years. In this work, hy...
متن کاملAbsorption Spectra of Phytochrome Intermediates
Native phytochrome (124kdalton) was isolated from etiolated seedlings o f Avena sativa L. cv. Pirol (Baywa, Munich). From low temperature spectra (0 °C to — 165°C ) o f phytochrom e samples irradiated either with red or far-red light, spectra o f intermediates were calculated. Both absorption bands o f the phytochrome chromophore were reported. On the pathway P r i V r , native phytochrome does...
متن کاملModeling Absorption Spectra of Optically Switchable Azobenzenes
Azobenzenes have the unique ability to undergo reversible isomerization between two geometrical isomers (the straight trans form and the bent cis) when exposed to certain wavelengths of light, which provide energy for the change. Thus, when embedded in liquid crystal matrices, azobenzene derivatives can function as optically triggered switches regulating, for example, membrane permeability to g...
متن کاملOptical Absorption Spectra of Bipolarons
The absorption of large bipolarons is investigated using the path-integral method. The response of a bipolaron to an external electromagnetic field is derived in the framework of the memory function approach. The bipolaron optical absorption spectrum consists of a series of relatively narrow peaks. The peculiarities of the bipolaron optical absorption as a function of the frequency of the elect...
متن کاملUV absorption spectra of polystyrene
Polystyrene (PSt) exhibits a new UV absorption band at around 290nm in comparison with ethylbenzene, which is attributed to associative interaction between pendant phenyl groups, similar absorption bands are also observed for polymers of styrene derivatives. The UV spectra suggest charge-transfer complex formation between the polymeric and monomeric donors with electron-acceptor tetracyanoethyl...
