Chain L ( RBL_TOBAC | P00876)
| molecular function |
|---|
| | GO:0016829 | | lyase activity | | Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. They differ from other enzymes in that two substrates are involved in one reaction direction, but only one in the other direction. When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring. |
| | GO:0000287 | | magnesium ion binding | | Interacting selectively and non-covalently with magnesium (Mg) ions. |
| | GO:0046872 | | metal ion binding | | Interacting selectively and non-covalently with any metal ion. |
| | GO:0004497 | | monooxygenase activity | | Catalysis of the incorporation of one atom from molecular oxygen into a compound and the reduction of the other atom of oxygen to water. |
| | 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:0016984 | | ribulose-bisphosphate carboxylase activity | | Catalysis of the reaction: D-ribulose 1,5-bisphosphate + CO2 + H2O = 2 3-phospho-D-glycerate. |
| biological process |
|---|
| | GO:0015977 | | carbon fixation | | A metabolic process in which carbon (usually derived from carbon dioxide) is incorporated into organic compounds (usually carbohydrates). |
| | 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:0009853 | | photorespiration | | A light-dependent catabolic process occurring concomitantly with photosynthesis in plants (especially C3 plants) whereby dioxygen (O2) is consumed and carbon dioxide (CO2) is evolved. The substrate is glycolate formed in large quantities in chloroplasts from 2-phosphoglycolate generated from ribulose 1,5-bisphosphate by the action of ribulose-bisphosphate carboxylase; the glycolate enters the peroxisomes where it is converted by glycolate oxidase to glyoxylate which undergoes transamination to glycine. This then passes into the mitochondria where it is decarboxylated forming one molecule of serine for every two molecules of glycine. This pathway also exists in photosynthetic bacteria. |
| | GO:0015979 | | photosynthesis | | The synthesis by organisms of organic chemical compounds, especially carbohydrates, from carbon dioxide (CO2) using energy obtained from light rather than from the oxidation of chemical compounds. |
| | GO:0019253 | | reductive pentose-phosphate cycle | | The fixation of carbon dioxide (CO2) as glucose in the chloroplasts of C3 plants; uses ATP and NADPH formed in the light reactions of photosynthesis; carbon dioxide reacts with ribulose 1,5-bisphosphate (catalyzed by the function of ribulose-bisphosphate carboxylase) to yield two molecules of 3-phosphoglycerate; these are then phosphorylated by ATP to 1,3-bisphosphateglyceraldehyde which, in turn, is then reduced by NADPH to glyceraldehyde 3-phosphate. The glyceraldehyde 3-phosphate is converted to fructose 5-phosphate and ribulose 5-phosphate by aldolase and other enzymes; the ribulose 5-phosphate is phosphorylated by ATP to ribulose 1,5-bisphosphate. |
| 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: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. |
