Isolation and Characterization of a Light-Harvesting Chlorophyll a/b Protein Complex Associated with Photosystem I [PDF]

open access: yesPlant Physiology, 1984
A chlorophyll a/b protein complex has been isolated from a resolved native photosystem I complex by mildly dissociating sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The chlorophyll a/b protein contains a single polypeptide of molecular weight 20 kilodaltons, and has a chlorophyll a/b ratio of 3.5 to 4.0. The visible absorbance spectrum of

Analysis of the chloroplast protein kinase Stt7 during state transitions.

open access: yesPLoS Biology, 2009
State transitions allow for the balancing of the light excitation energy between photosystem I and photosystem II and for optimal photosynthetic activity when photosynthetic organisms are subjected to changing light conditions.

Role of plastid protein phosphatase TAP38 in LHCII dephosphorylation and thylakoid electron flow. [PDF]

open access: yesPLoS Biology, 2010
Short-term changes in illumination elicit alterations in thylakoid protein phosphorylation and reorganization of the photosynthetic machinery. Phosphorylation of LHCII, the light-harvesting complex of photosystem II, facilitates its relocation to ...

NOE distance and dihedral angle restraints to calculate the solution structure of the NDH-1 complex subunit CupS from Thermosynechococcus elongatus

open access: yesData in Brief, 2016
Here, we have compiled a nuclear magnetic resonance (NMR)-derived set of nuclear Overhauser enhancement (NOE) distance and dihedral angle restraints that allow for the calculation of the structure of the NDH-1 complex subunit CupS from ...
