Photosynthetic Reaction Center Complex Proteins

Medical Definition: Protein complexes that take part in the process of PHOTOSYNTHESIS. They are found in the THYLAKOID MEMBRANES of PLANTS and other photosynthetic organisms. There are two major complexes involved in the photosynthetic process called PHOTOSYSTEM I and PHOTOSYSTEM II.
Also Called: Photosynthetic Complexes,Photosynthetic Reaction Center, Bacterial,Photosynthetic Reaction Center, Plant,Photosynthetic Reaction Centers
Previously Indexed: Chlorophyll (1966-1990),Plant Proteins (1966-2003)
Photosynthetic Reaction Center Complex Proteins Categories.
Canadian Medical Guide Definition Cytochrome b6f Complex - A protein complex that includes CYTOCHROME B6 and CYTOCHROME F. It is found in the THYLAKOID MEMBRANE and plays an important role in process of PHOTOSYNTHESIS by transfering electrons from PLASTOQUINONE to PLASTOCYANIN or CYTOCHROME C6. The transfer of electrons is coupled to the transport of PROTONS across the membrane.
Canadian Medical Guide Definition Light-Harvesting Protein Complexes - Complexes containing CHLOROPHYLL and other photosensitive molecules. They serve to capture energy in the form of PHOTONS are generally found as components of the PHOTOSYSTEM I PROTEIN COMPLEX or the PHOTOSYSTEM II PROTEIN COMPLEX.
Canadian Medical Guide Definition Photosystem I Protein Complex - A large multisubunit protein complex that is found in the THYLAKOID MEMBRANE. It uses light energy derived from LIGHT-HARVESTING PROTEIN COMPLEXES to drive electron transfer reactions that result in either the reduction of NADP to NADPH or the transport of PROTONS across the membrane.
Canadian Medical Guide Definition Photosystem II Protein Complex - A large multisubunit protein complex found in the THYLAKOID MEMBRANE. It uses light energy derived from LIGHT-HARVESTING PROTEIN COMPLEXES to catalyze the splitting of WATER into DIOXYGEN and of reducing equivalents of HYDROGEN.
