Association of chlorophyll a/b-binding Pcb proteins with photosystems I and II in Prochlorothrix hollandica

Vladimir A. Boichenko, Alexander V. Pinevich, Igor N. Stadnichuk

BBA - Bioenergetics > 2007 > 1767 > 6 > 801-806

Action spectra for photosystem II (PSII)-driven oxygen evolution and of photosystem I (PSI)-mediated H ₂ photoproduction and photoinhibition of respiration were used to determine the participation of chlorophyll (Chl) a/b-binding Pcb proteins in the functions of pigment apparatus of Prochlorothrix hollandica. Comparison of the in situ action spectra with absorption spectra of PSII and PSI...

Functions of carotenoids in xanthorhodopsin and archaerhodopsin, from action spectra of photoinhibition of cell respiration

BBA - Bioenergetics > 2006 > 1757 > 12 > 1649-1656

The recent discovery of a carotenoid light-harvesting antenna in xanthorhodopsin, a retinal-based proton pump in Salinibacter ruber, made use of photoinhibition of respiration in whole cells to obtain action spectra [Balashov et al. Science 309, (2005) 2061–2064]. Here we provide further details of this phenomenon, and compare action spectra in three different systems where carotenoids have different...

Volume changes and electrostriction in the primary photoreactions of various photosynthetic systems: estimation of dielectric coefficient in bacterial reaction centers and of the observed volume changes with the Drude–Nernst equation

David Mauzerall, Jian-Min Hou, Vladimir A. Boichenko

Photosynthesis Research > 2002 > 74 > 2 > 173-180

Photoacoustics (PA) allows the determination of enthalpy and volume changes of photoreactions in photosynthetic reaction centers on the 0.1–10 μs time scale. These include the bacterial centers from Rb. sphaeroides, PS I and PS II centers from Synechocystis and in whole cells. In vitro and in vivo PA data on PS I and PS II revealed that both the volume change (–26 A³) and reaction enthalpy (–0.4 eV)...

Functional characteristics of chlorophyll d-predominating photosynthetic apparatus in intact cells of Acaryochloris marina

Vladimir A. Boichenko, Vyacheslav V. Klimov, Hideaki Miyashita, Shigetoh Miyachi

Photosynthesis Research > 2000 > 65 > 3 > 269-277

Functional organization of the photosynthetic apparatus in the unique chlorophyll d-predominating prokaryote, Acaryochloris marina, was studied using polarographic measurements of single-turnover flash yields, action spectra and optical cross sections for PS-specific reactions. O₂ evolution was indicative of PS II activity, while reversible photoinhibition of respiratory O₂ uptake under aerobic conditions...

The functional organization of competent photosynthetic units in developing thylakoids from intermittent-light grown pea as well as in the unstacked, stacked and phosphorylated stacked thylakoids from its mature chloroplasts was characterized by polarographic measurements of action spectra, reaction centre contents and optical cross-sections for PS I-mediated O2 uptake and PS II-mediated O2 evolution...

Verification of the Z-scheme in Chlamydomonas mutants with Photosystem I deficiency

Vladimir A. Boichenko, Klaus P. Bader

Photosynthesis Research > 1998 > 56 > 1 > 113-115

In conflict with the Z-scheme of photosynthesis, it has recently been reported [Greenbaum et al. Nature (1995) 376: 438–441; Lee et al. Science (1996) 273: 364–367] that Photosystem II can drive ferredoxin reduction and photoautotrophic growth in some mutants of Chlamydomonas lacking detectable Photosystem I reaction centre, P700. Using the same mutants, B4 and F8, here we report that action spectra...
