Arabidopsis STN7 Kinase Provides a Link between Short- and Long-Term Photosynthetic Acclimation [PDF]

, 2009
Flowering plants control energy allocation to their photosystems in response to light quality changes. This includes the phosphorylation and migration of light-harvesting complex II (LHCII) proteins (state transitions or short-term response) as well as ...

Spectroscopic characterization of reaction centers of the (M)Y210W mutant of the photosynthetic bacterium Rhodobacter sphaeroides [PDF]

, 1994
The tyrosine-(M)210 of the reaction center of Rhodobacter sphaeroides 2.4.1 has been changed to a tryptophan using site-directed mutagenesis. The reaction center of this mutant has been characterized by low-temperature absorption and fluorescence ...

REACTIVITY OF CHLOROPHYLL a/b-PROTEINS AND MICELLAR TRITON X-100 COMPLEXES OF CHLOROPHYLLS a OR b WITH BOROHYDRIDE [PDF]

, 1989
The reaction of several plant chlorophyll-protein complexes with NaBH4 has been studied by absorption spectroscopy. In all the complexes studied, chlorophyll b is more reactive than Chi a, due to preferential reaction of its formyl substituent at C-7 ...

Modified reaction centers from Rhodobacter sphaeroides R26 [PDF]

, 1990
Monomeric bacteriochlorophylls BA and BB in photosynthetic reaction centers from Rhodobacter sphaeroides R26 were exchanged with (132-hydroxy-) bacteriochlorophylls containing a 3-vinyl- or 3-(α-hydroxyethyl)-substituent instead of the 3-acetyl group ...

Physiological and Mechanistic Studies of Phototrophic Fe(II) Oxidation in Purple Non-sulfur Bacteria [PDF]

, 2007
Phototrophic Fe(II)-oxidizing bacteria use electrons from ferrous iron [Fe(II)] and energy from light to drive reductive CO₂ fixation. This metabolism is thought to be ancient in origin, and plays an important role in environmental iron cycling. It has

Comparison of the α and β isomeric forms of the detergent n-dodecyl-D-maltoside for solubilizing photosynthetic complexes from pea thylakoid membranes [PDF]

, 2012
Mild non-ionic detergents are indispensable in the isolation of intact integral membrane proteins and protein-complexes from biological membranes. Dodecylmaltoside (DM) belongs to this class of detergents being a glucoside-based surfactant with a bulky ...

Direct and indirect electron transfer from cytochromes c and c₂ to the photosynthetic reaction center in pigment‐protein complexes isolated from Rhodocyclus gelatinosus

FEBS Letters, 1988
Electron transfer from soluble cytochromes c and c 2 to the photo‐oxidized bacteriochlorophyll dimer was studied in photosynthetic reaction center (RC) complexes and RC‐B870 complexes isolated from Rhodocyclus gelatinosus. In the RC‐B870 complex which consists of 6 polypeptides including a bound cytochrome subunit, cytochrome c from horse heart or ...
