IPR017486 is a Photosystem II CP47 reaction centre protein.
<p>This entry contains the photosystem II P680 chlorophyll A apoprotein, PsbB.</p> <p>Photosystem II light-harvesting proteins are the intrinsic transmembrane antenna proteins CP43 (PsbC) and CP47 (PsbB) found in the reaction centre of PSII. These polypeptides bind to chlorophyll a and beta-carotene and pass the excitation energy on to the reaction centre [[cite:PUB00015360]]. This family also includes the iron-stress induced chlorophyll-binding protein CP43 (IsiA), which evolved in cyanobacteria from a PSII protein to cope with light limitations and stress conditions [[cite:PUB00015361]].</p>

GO predictions are based solely on the InterPro-to-GO mappings published by EMBL-EBI, which are in turn based on the mapping of predicted domains to the InterPro dataset. The InterPro-to-GO mapping was last updated on , while the GO metadata was last updated on .
| GO term | Namespace | Name | Definition | Relationships |
|---|---|---|---|---|
| Cellular component | Photosystem II | A photosystem that contains a pheophytin-quinone reaction center with associated accessory pigments and electron carriers. In cyanobacteria and chloroplasts, in the presence of light, PSII functions as a water-plastoquinone oxidoreductase, transferring electrons from water to plastoquinone, whereas other photosynthetic bacteria carry out anoxygenic photosynthesis and oxidize other compounds to re-reduce the photoreaction center. | ||
| Biological process | Photosynthetic electron transport in photosystem II | A photosynthetic electron transport chain in which electrons move from the primary electron acceptor (Quinone, Q) through a chain of electron transport molecules in the thylakoid membrane until they reach the ultimate electron acceptor of Photosystem II, which is plastocyanin (PC). The electron is then passed to the P700 chlorophyll a molecules of the reaction centre of photosystem I. | ||
| Biological process | 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. | ||
| Cellular component | Membrane | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. | ||
| Molecular function | Chlorophyll binding | Interacting selectively and non-covalently with chlorophyll; any compound of magnesium complexed in a porphyrin (tetrapyrrole) ring and which functions as a photosynthetic pigment. | ||
| Molecular function | Electron transporter, transferring electrons within the cyclic electron transport pathway of photosynthesis activity | Enables the directed movement of electrons within the cyclic electron transport pathway of photosynthesis. |
