molecular function |
| GO:0016491 | | oxidoreductase activity | | Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced. |
| GO:0005515 | | protein binding | | Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules). |
| GO:0046422 | | violaxanthin de-epoxidase activity | | Catalysis of the reaction: violaxanthin + 2 ascorbate = zeaxanthin + 2 dehydroascorbate + 2 H2O; and antheraxanthin + ascorbate = zeaxanthin + dehydroascorbate + H2O. |
biological process |
| GO:0015994 | | chlorophyll metabolic process | | The chemical reactions and pathways involving chlorophyll, any compound of magnesium complexed in a porphyrin (tetrapyrrole) ring and which functions as a photosynthetic pigment. |
| GO:0006631 | | fatty acid metabolic process | | The chemical reactions and pathways involving fatty acids, aliphatic monocarboxylic acids liberated from naturally occurring fats and oils by hydrolysis. |
| GO:0055114 | | oxidation-reduction process | | A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons. |
| GO:0009408 | | response to heat | | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a heat stimulus, a temperature stimulus above the optimal temperature for that organism. |
| GO:0010028 | | xanthophyll cycle | | A cyclic series of interconversions involving three xanthophylls, violoxanthin, antheraxanthin, and zeaxanthin. The xanthophyll cycle is involved in regulating energy dissipation in light harvesting complex II. |
cellular component |
| GO:0009507 | | chloroplast | | A chlorophyll-containing plastid with thylakoids organized into grana and frets, or stroma thylakoids, and embedded in a stroma. |
| GO:0009534 | | chloroplast thylakoid | | 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. |
| GO:0009535 | | chloroplast thylakoid membrane | | The pigmented membrane of a chloroplast thylakoid. An example of this component is found in Arabidopsis thaliana. |
| GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| GO:0009536 | | plastid | | 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. |
| GO:0009579 | | thylakoid | | 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. |
| GO:0031977 | | thylakoid lumen | | The volume enclosed by a thylakoid membrane. |
