Photoinhibition of photosystem I

Planta, 2005
Photosystem 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 complex

Photosynthesis Research, 1988
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.

The Composition and Organization of Photosystem I

Journal of Basic and Clinical Physiology and Pharmacology, 1991
Photosystem I, extensively studied in the past decade, was shown to be homologous in all photosynthetic organisms of the higher plants type. Its core complex was found to be highly conserved through evolution from cyanobacteria to higher plants. The genes coding for the subunits of CCI were isolated and the resulting sequences provided information ...

Photosystem I inhibition by polycations

Biochemical and Biophysical Research Communications, 1971
Abstract 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.

Interaction of ascorbate with photosystem I

Photosynthesis Research, 2014
Ascorbate is one of the key participants of the antioxidant defense in plants. In this work, we have investigated the interaction of ascorbate with the chloroplast electron transport chain and isolated photosystem I (PSI), using the EPR method for monitoring the oxidized centers [Formula: see text] and ascorbate free radicals. Inhibitor analysis of the
