Selective extraction of antenna chlorophylls, carotenoids and quinones from photosystem I reaction center.
By the ether treatment of lyophilized PSI pigment-protein complexes, all the carotenoids and the secondary acceptor phylloquinone (A1), and more than 90% of the Chl were removed to yield the PSI complex with 9-11 molecules of Chl per reaction-center unit. The complexes retained the primary electron donor and acceptor (P700 and A0), in addition to three FeS clusters (F(X), F(A) and F(B)), and sh...
متن کاملElectric field effects on the chlorophylls, pheophytins, and beta-carotenes in the reaction center of photosystem II.
We present an electric field modulated absorption spectroscopy (Stark effect) study of isolated photosystem II reaction center complexes, including a preparation in which the inactive pheophytin H(B) was exchanged for 13(1)-deoxo-13(1)-hydroxy-pheophytin. The results reveal that the Stark spectrum of the Q(x) and Q(y) transitions of the pheophytins has a second-derivative line shape, indicating...
متن کاملCytochrome c Provides an Electron-Funneling Antenna for Efficient Photocurrent Generation in a Reaction Center Biophotocathode
The high quantum efficiency of photosynthetic reaction centers (RCs) makes them attractive for bioelectronic and biophotovoltaic applications. However, much of the native RC efficiency is lost in communication between surface-bound RCs and electrode materials. The state-of-the-art biophotoelectrodes utilizing cytochrome c (cyt c) as a biological wiring agent have at best approached 32% retained...
متن کاملStark effect spectroscopy of carotenoids in photosynthetic antenna and reaction center complexes.
The effects of electric fields on the absorption spectra of the carotenoids spheroidene and spheroidenone in photosynthetic antenna and reaction center complexes (wild-type and several mutants) from purple non-sulfur bacteria are compared with those for the isolated pigments in organic glasses. In general, the field effects are substantially larger for the carotenoid in the protein complexes th...
متن کاملDesigning two models for comprehensive center of excellence and center of excellence in the field of medical sciences in Iran
Background: Despite exist several centers of excellence in the various medical field in the country, most of them lack a single procedure and organizational structures in their functioning, organizing, targeting, etc. So the study aimed to design an organizational model that meets the goals and mission of them in the field of medical sciences. Methods: This qualitative and applied research was...
