Fluorescence property of photosystem II protein complexes bound to a gold nanoparticle

Faraday Discussions, 2017
Development of an efficient photo-anode system for water oxidation is key to the success of artificial photosynthesis. We previously assembled photosystem II (PSII) proteins, which are an efficient natural photocatalyst for water oxidation, on a gold nanoparticle (GNP) to prepare a PSII–GNP conjugate as an anode system in a light-driven water-splitting

Distribution of the chlorophyll spectral forms in the chlorophyll-protein complexes of photosystem II antenna

Biochemistry, 1993
The chlorophyll-protein complexes that form the antenna system of photosystem II have been purified and analyzed in terms of the commonly observed chlorophyll spectral forms. With the exception of chlorophyll b, which is known to be associated with the complexes comprising the outer antenna (LHCII, CP24, CP26, CP29), the spectral forms occur with ...

The effect of norflurazon on protein composition and chlorophyll organization in pigment–protein complex of Photosystem II

Photosynthesis Research, 2005
The pyridazinone-type herbicide norflurazon SAN 9789 inhibiting the biosynthesis of long-chain carotenoids results in significant decrease in PS II core complexes and content of light-harvesting complex (LHC) polypeptides in the 29.5-21 kDa region. The Chl a forms at 668, 676, and 690 nm that belong to LHC and antenna part of PS I disappear completely ...

Isolation of manganese-containing protein complex from photosystem II preparations of spinach

Biochemistry, 1986
Purified 125I-labeled 33-kDa protein binds to calcium-washed photosystem II preparations at high-affinity and low-affinity binding sites. Filling 70% of the high-affinity site with 33-kDa protein induces 63% of the maximum achievable reconstitution of O2-evolving activity.

Multiple copies of the PsbQ protein in a cyanobacterial photosystem II assembly intermediate complex

Photosynthesis Research, 2015
Photosystem II (PSII) undergoes frequent damage owing to the demanding electron transfer chemistry it performs. To sustain photosynthetic activity, damaged PSII undergoes a complex repair cycle consisting of many transient intermediate complexes. By purifying PSII from the cyanobacterium Synechocystis sp.

A study of Photosystem II fluorescence emission in terms of the antenna chlorophyll-protein complexes

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1993
Abstract Fluorescence emission spectra for the seven chlorophyll-protein complexes comprising the antenna system of Photosystem II (PS II) have been measured. All four outer antenna complexes (LHC II, CP24, CP26, CP29) have relatively greater emission near 648 nm and 680 nm with respect to the inner antenna complexes (CP43, CP47, D1/D2/cyt b-559 ...

A novel protein domain is important for photosystem II complex assembly and photoautotrophic growth in angiosperms

Molecular Plant, 2023
Photosystem II (PSII) is a multi-subunit protein complex of the photosynthetic electron transport chain that is vital to photosynthesis. Although the structure, composition, and function of PSII have been extensively studied, its biogenesis mechanism remains less understood.

Co-translational Assembly of the D1 Protein into Photosystem II Complexes

1998
Chloroplast-encoded D1 and D2 proteins, the heterodimer reaction centre polypeptides of photosystem II (PS II) bind all the components necessary for the primary charge separation. The D1 protein has an unusually high turnover rate as compared to the other chloroplast proteins (1,2).

Photosystem II activity and pigment-protein complexes in flashed bean leaves

Plant Science Letters, 1973
Abstract Bean leaves exposed to cycles of 2 min light—118 min dark, (1) can photoreduce cytochrome f ; (2) have cytochrome b -559 HP ; (3) have a DCMU (3-[3′,4′-dichlorophenyl]-1,1-dimethylurea)-sensitive Hill reaction. Detergent extracts of the plastids show only pigment-protein complex I.

A study of an energy harvesting device based on photosystem-II protein complex

2014 IEEE International Symposium on Bioelectronics and Bioinformatics (IEEE ISBB 2014), 2014
In this study, we accomplished a solid-state photosystem-II (PSII) device for bio-inherited solar energy-harvesting device. With solid-state PSII embedded, this is an innovative device with better life time and stable performance than previous photosystem based devices.
