The protein transport machinery of the chloroplast outer membrane that contains at least three components Toc159, Toc75 and Toc34, interacts with precursor proteins which are imported into the chloroplast in a GTP dependant manner. The region of a chloroplast to which the DNA is confined. 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. A ribosome contained within a chloroplast. The region between the inner and outer lipid bilayers of a chloroplast envelope. A circular DNA molecule containing chloroplast encoded genes. The pigment-protein complex primarily associated to PSII in higher plants, green algae and cyanobacteria that directly transfers electrons to the reaction center. The translocon of the inner envelope of chloroplasts, which facilitates the import of proteins across the chloroplast inner membrane. The pigmented membrane of a chloroplast thylakoid. An example of this component is found in Arabidopsis thaliana. Any member of a family of organelles found in the cytoplasm of plants and some protists, which are membrane-bounded and contain DNA. Plant plastids develop from a common type, the proplastid. Any constituent part of a chloroplast, a chlorophyll-containing plastid with thylakoids organized into grana and frets, or stroma thylakoids, and embedded in a stroma. A complex, located in the chloroplast, containing either both large and small subunits or just small subunits which carries out the activity of producing 3-phosphoglycerate from carbon dioxide and ribulose-1,5-bisphosphate. An example of this component is found in Arabidopsis thaliana. Located such that some or all of the gene product itself penetrates at least one phospholipid bilayer of the chloroplast outer membrane. May also refer to the state of being buried in the bilayer with no exposure outside the bilayer. Any constituent part of a plastid, a member of a family of organelles found in the cytoplasm of plants and some protists, which are membrane-bounded and contain DNA. Plant plastids develop from a common type, the proplastid. Located in the chloroplast outer 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. A Clp endopeptidase complex located in the chloroplast. Located such that some or all of the gene product itself penetrates at least one phospholipid bilayer of the chloroplast inner membrane. May also refer to the state of being buried in the bilayer with no exposure outside the bilayer. The space enclosed by the double membrane of a chloroplast but excluding the thylakoid space. It contains DNA, ribosomes and some temporary products of photosynthesis. Located in the chloroplast inner 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. Sac-like membranous structures (cisternae) in a chloroplast combined into stacks (grana) and present singly in the stroma (stroma thylakoids or frets) as interconnections between grana. An example of this component is found in Arabidopsis thaliana. Plastoglobules (PG) are lipoprotein particles present in chloroplasts. They are rich in non-polar lipids (triglycerides, esters) as well as in prenylquinones, plastoquinone and tocopherols. Plastoglobules are often associated with thylakoid membranes, suggesting an exchange of lipids with thylakoids. 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. All non-F1 subunits of the chloroplast hydrogen-transporting ATP synthase, including integral and peripheral chloroplast thylakoid membrane proteins. 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. 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. A protein complex whose composition varies amongst species; in rice it probably exists in a homo-tetramer to homo-hexamer form and in Gram negative bacteria as a dimer. Functions in the hydrolysis of alpha-(1,6)-D-glucosidic branch linkages. Isoamylases in plants are intracellular and probably chloroplast localized. Either of the lipid bilayers that surround a chloroplast and form the chloroplast envelope. An ADPG pyrophosphorylase complex found in the chloroplast. The double lipid bilayer enclosing the chloroplast and separating its contents from the rest of the cytoplasm; includes the intermembrane space. Any constituent part of the cytoplasm, all of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. A proton-transporting ATP synthase complex found in the chloroplast thylakoid membrane; it catalyzes the phosphorylation of ADP to ATP during photo-phosphorylation. A protein complex that possesses ferredoxin:thioredoxin reductase activity. The protein complex that catalyzes the phosphorylation of ADP to ATP in chloroplasts. Lipid bodies localized within the chloroplast stroma. Distinct stack of lamellae seen within chloroplasts. Grana contain the pigments, electron transfer compounds, and enzymes essential to the light-dependent reactions of photosynthesis. The large subunit of a ribosome contained within a chloroplast. Plant storage body for amylose and amylopectin, 1-100um in diameter, and located in chloroplasts. Also contains small amounts of enzymes, amino acids, lipids and nucleic acids. The shape of the grain varies widely amongst species, but is often spherical or disk-shaped. The cavity enclosed within the chloroplast thylakoid membrane. An example of this component is found in Arabidopsis thaliana. The small subunit of a ribosome contained within a chloroplast. A constituent part of an intracellular organelle, an organized structure of distinctive morphology and function, occurring within the cell. Includes constituent parts of the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton but excludes the plasma membrane. Protein translocon complex at the chloroplast outer membrane. A heterotrimeric enzyme complex composed of three subunits, all of which are required for enzyme activity, which catalyzes the chelation of Mg by proto IX in an ATP-dependent manner. A chlorophyll-containing plastid with thylakoids organized into grana and frets, or stroma thylakoids, and embedded in a stroma.
