The volume enclosed by a thylakoid membrane. A pigment protein complex that forms part of the photosystem II associated light-harvesting complex II; contains two proteins (usually about 28 and 27 kDa), and may contain a third; peripherally located relative to other LHC polypeptides. A thylakoid membrane complex of chlorophylls a and b together with chlorophyll a-b binding proteins. In addition, LHCs contain a number of other proteins, the function of which is speculative, together with accessory pigments. The LHCs capture and transfer energy to photosystems I and II. An example of this is found in Arabidopsis thaliana. Pigment-protein complex primarily associated to PSII in plants, green algae and cyanobacteria. Involved in state transitions that cause migration to PSI under certain environmental conditions such as high light. Penetrating at least one phospholipid bilayer of a thylakoid membrane. May also refer to the state of being buried in the bilayer with no exposure outside the bilayer. A complex, composed of a cluster of manganese, calcium and chloride ions bound to extrinsic proteins, that catalyzes the splitting of water to O2 and 4 H+. In cyanobacteria there are five extrinsic proteins in OEC (PsbO, PsbP-like, PsbQ-like, PsbU and PsbV), while in plants there are only three (PsbO, PsbP and PsbQ). Located in a thylakoid membrane such that some covalently attached portion of the gene product, for example part of a peptide sequence or some other covalently attached moiety such as a GPI anchor, spans or is embedded in one or both leaflets of the membrane. The pigment-protein complex primarily associated to PSII in higher plants, green algae and cyanobacteria that directly transfers electrons to the reaction center. A complex, located in the plasma membrane-derived thylakoid, containing either both large and small subunits or just small subunits. It carries out the activity of producing 3-phosphoglycerate from carbon dioxide and ribulose-1,5-bisphosphate. The living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm. Any constituent part of a thylakoid, a sac-like vesicle that bears the photosynthetic pigments in photosynthetic organisms. A membranous cellular structure that bears the photosynthetic pigments in plants, algae, and cyanobacteria. In cyanobacteria thylakoids are of various shapes and are attached to, or continuous with, the plasma membrane. In eukaryotes they are flattened, membrane-bounded disk-like structures located in the chloroplasts; in the chloroplasts of higher plants the thylakoids form dense stacks called grana. Isolated thylakoid preparations can carry out photosynthetic electron transport and the associated phosphorylation. The catalytic sector of the mitochondrial hydrogen-transporting ATP synthase; it comprises the catalytic core and central stalk, and is peripherally associated with the chloroplast thylakoid membrane when the entire ATP synthase is assembled. The chloroplast F0 domain contains three alpha, three beta, one gamma, one delta, and one epsilon subunits. A protein complex, located in the membrane-derived thylakoid, containing the P680 reaction center. In the light, PSII functions as a water-plastoquinone oxidoreductase, transferring electrons from water to plastoquinone. All non-F1 subunits of the chloroplast hydrogen-transporting ATP synthase, including integral and peripheral chloroplast thylakoid membrane proteins. Loosely bound to one surface of a thylakoid membrane, but not integrated into the hydrophobic region. An integral chloroplast membrane complex containing the P680 reaction center. In the light, PSII functions as a water-plastoquinone oxidoreductase, transferring electrons from water to plastoquinone. A protein complex located in the plasma membrane-derived thylakoid. The photosystem functions as a light-dependent plastocyanin-ferredoxin oxidoreductase, transferring electrons from plastocyanin to ferredoxin. Examples of this complex are found in bacterial species. Complex that transfers electrons from reduced plastoquinone to oxidized plastocyanin and translocates protons from the stroma to the lumen. The complex contains a core structure of three catalytic subunits: cytochrome b, the Rieske iron sulfur protein (ISP), and cytochrome f, which are arranged in an integral membrane-bound dimeric complex; additional subunits are present, and vary among different species. Photosystem located in the chloroplast that functions as a light-dependent plastocyanin-ferredoxin oxidoreductase, transferring electrons from plastocyanin to ferredoxin. An example of this is found in Arabidopsis thaliana. The pigmented membrane of any thylakoid. A proton-transporting ATP synthase complex found in the chloroplast thylakoid membrane; it catalyzes the phosphorylation of ADP to ATP during photo-phosphorylation. The protein complex that catalyzes the phosphorylation of ADP to ATP in chloroplasts. Any constituent part of a cell, the basic structural and functional unit of all organisms. Any constituent part of the living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm. Any of the granules, approximately 32 nm x 48 nm and consisting of highly aggregated phycobiliproteins, that are attached in arrays to the external face of a thylakoid membrane in algae of the phyla Cyanophyta and Rhodophyta, where they function as light-harvesting devices in photosynthesis. Excitation energy in the phycobilisome flows in the sequence: phycoerythrin, phycocyanin, allophycocyanin before passing to the antenna chlorophyll of photosystem II.
