The Plasticity of Photosystem I.
Plant and Cell Physiology, 2021 Most of life’s energy comes from sunlight, and thus, photosynthesis underpins the survival of virtually all life forms. The light-driven electron transfer at photosystem I (PSI) is certainly the most important generator of reducing power at the ...

Photosystem I is an integral component of the thylakoid membrane which catalyzes the photoreduction of ferredoxin using plastocyanin or cytochrome c as electron donor. In higher plants, the photosystem I complex is composed of eight protein subunits, chlorophyll a, carotenoids, phylloquinone and bound iron sulfur clusters.

Photoinhibition of photosystem I
Planta, 2005Photosystem I (PSI) is a large pigment-protein complex consisting of about 18 different subunits in plants. Recently, the structure of PSI isolated from pea was solved by X-ray crystallography at a resolution of 4.4 A (Ben-Shem et al. 2003). This work has highlighted the structural similarities and differences between plant PSI and cyanobacterial PSI ...

Photosystem I mediates light‐induced electron transport from reduced plastocyanin in the thylakoid lumen to oxidized ferredoxin in the stroma. Photosystem I is located in the stroma lamellae of the thylakoid system and consists of a peripheral light‐harvesting pigment‐protein complex and a core complex carrying the electron transfer components and ...

Photosystem I inhibition by polycations
Biochemical and Biophysical Research Communications, 1971Abstract Histones and other polycations inhibit the photosystem I reactions of isolated chloroplasts. Photosystem II activity is readily measured in preparations where histone has completely blocked photosystem I activity. Histone inhibition is prevented by preincubation of the chloroplasts in solutions containing salt.

Primary photochemistry in photosystem-I
Photosynthesis Research, 1985In this review, the main research developments that have led to the current simplified picture of photosystem I are presented. This is followed by a discussion of some conflicting reports and unresolved questions in the literature. The following points are made: (1) the evidence is contradictory on whether P700, the primary donor, is a monomer or dimer

Structure of cyanobacterial Photosystem I
Photosynthesis Research, 2005Photosystem I is one of the most fascinating membrane protein complexes for which a structure has been determined. It functions as a bio-solar energy converter, catalyzing one of the first steps of oxygenic photosynthesis. It captures the light of the sun by means of a large antenna system, consisting of chlorophylls and carotenoids, and transfers the ...

Abstract Recent work on the structure of photosystem I (PS I) is reviewed in historical context. Composition and methods of preparation of the reaction center, core and antennae are described. Emphasis is on the polypeptide composition of the various parts of the photosystem, especially the core, which also includes the reaction center.
