Photosystem I [1] is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin . The photosystem I proteins are responsible for the precise arrangement of cofactors and determine redox properties of the electron transfer centers. With the availability of genomic information and the structure of photosystem I, one can now probe the functions of photosystem I proteins and cofactors. Photosystem I (PS I) is a chlorophyll (Chl)–protein complex that functions as a light-driven plastocyanin:ferredoxin oxidoreductase. Electron transfer from plastocyanin ( E m ≈ +370 mV) to ferredoxin ( E m ≈ −430 mV) would normally be very endergonic (Δ G ≈ +87 kJ/mol), but is rendered favorable by coupling to absorption of a photon of visible light. 2007-05-01 · Structure, function and regulation of plant photosystem I 1.

Structure and Function of Intact Photosystem 1 Monomers from the Cyanobacterium Thermosynechococcus elongatus Photosystem II (PSII) is a light-driven water:plastoquinone oxidoreductase that uses light energy to abstract electrons from H(2)O, generating O(2) and a proton gradient subsequently used for ATP formation. It consists of a core antenna complex that captures photons, and an electron transfer chain that converts photonic excitation into a charge separation. 2010-11-11 About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators Core Difference Between Photosystem I and Photosystem II.

Photosystem I is the light-driven plastocyanin-ferredoxin oxidoreductase in the thylakoid membranes of cyanobacteria and chloroplasts. In recent years, sophisticated spectroscopy, molecular genetics, and biochemistry have been used to understand the light conversion and electron transport functions of photosystem I.

Core Composition: The PSI is made up of two subunits which are psaA and psaB. Photosystem. Photosystems are the functional units for photosynthesis, defined by a particular pigment organization and association patterns, whose work is the absorption and transfer of light energy, which implies transfer of electrons. From:Postharvest Physiology and Biochemistry of Fruits and Vegetables, 2019. Das Photosystem I (PS I) ist ein Proteinkomplex aus mehreren Membranproteinen, der im Zuge der Photosynthese eine Oxidation von Plastocyanin und die Reduktion von Ferredoxin durch absorbierte Photonen katalysiert. Es befindet sich bei Pflanzenzellen in der Thylakoidmembran der Chloroplasten und besteht aus 15 Proteinen.
