Chloride binding proteins: mechanistic implications for the oxygen-evolving complex of Photosystem II

Photosynthesis Research, 1990
Chloride plays a key role in activating the photosynethetic oxygen-evolving complex (OEC) of Photosystem II, but the OEC is only one of many enzymes affected by this anion. Some of the mechanistic features of Cl(-) involvement in water-splitting resemble those of other proteins whose structure and chemistry are known in detail.

The status of cysteine residues in the extrinsic 33 kDa protein of spinach photosystem II complexes

Photosynthesis Research, 1988
Two cysteine residues of the extrinsic 33 kDa protein in the oxygen-evolving photosystemII (PS II) complexes were found to exist as cystine residues in situ. The 33 kDa protein, when reduced by 2-mercaptoethanol in either the presence or the absence of 6 M guanidine-HCl (Gdn-HCl), could not rebind with the CaCl2-treated PS II complexes, from which the ...

A manganese-copper-pigment-protein complex isolated from the photosystem II of Phaeodactylum tricornutum

Archives of Biochemistry and Biophysics, 1977
Abstract The diatom Phaeodactylum tricornutum has been grown in defined medium with known amounts of 54 Mn and Cu. The diatoms were then fractionated by mild procedures to isolate a metallo-pigment-protein complex. This complex had a molecular weight of 850,000 and probably was made up of 40 subunits of protein, 40 mol of chlorophyll a , 20 mol ...

Vectorial Charge Transfer Reactions in the Protein-Pigment Complex of Photosystem II

2017
The pigment-protein complex of photosystem II localized in the thylakoid membranes of higher plants, algae, and cyanobacteria is the main source of oxygen on Earth. The light-induced functioning of photosystem II is directly linked to electron and proton transfer across the membrane, which results in the formation of transmembrane electric potential ...

Synthesis and Assembly of the D1 Protein into Photosystem II:  Processing of the C-Terminus and Identification of the Initial Assembly Partners and Complexes during Photosystem II Repair

Biochemistry, 1997
In previous studies [van Wijk, K. J., Bingsmark, S., Aro, E.-M., & Andersson, B. (1995) J. Biol. Chem. 270, 25685-25695; van Wijk, K. J., Andersson, B., & Aro, E.-M. (1996) J. Biol. Chem 271, 9627-9636], we have demonstrated that D1 protein synthesized in isolated chloroplasts and thylakoids is incorporated into the photosystem II (PSII) core complex ...

Differential changes in degradation of chlorophyll–protein complexes of photosystem I and photosystem II during flag leaf senescence of rice

Plant Physiology and Biochemistry, 2005
The stability of chlorophyll-protein complexes of photosystem I (PSI) and photosystem II (PSII) was investigated by chlorophyll (Chl) fluorescence spectroscopy, absorption spectra and native green gel separation system during flag leaf senescence of two rice varieties (IIyou 129 and Shanyou 63) grown under outdoor conditions.

Photosystem II-Associated Protein Kinase Phosphorylates a Novel 6.3 kDa Protein Which Subsequently Dissociates From Photosystem II Core Complexes

1998
The enzymes responsible for reversible phosphorylation of components of photosynthetic complexes are presumed to be associated with the thylakoid membrane. Evidence supporting the presence of multiple protein kinases in this system is mounting. Phosphorylation appears to be redox-regulated with activity favoured by reducing conditions.
