| | psbA-2 | Photosystem q(b) protein; Photosystem II (PSII) is a light-driven water:plastoquinone oxidoreductase that uses light energy to abstract electrons from H(2)O, generating O(2) and a proton gradient subsequently used for ATP formation. It consists of a core antenna complex that captures photons, and an electron transfer chain that converts photonic excitation into a charge separation. The D1/D2 (PsbA/PsbA) reaction center heterodimer binds P680, the primary electron donor of PSII as well as several subsequent electron acceptors. (360 aa) |
| | psbD-2 | Photosystem II D2 protein. (352 aa) |
| | cpcB | Phycocyanin, beta subunit; Light-harvesting photosynthetic bile pigment-protein from the phycobiliprotein complex. (172 aa) |
| | cpcA | Phycocyanin, alpha subunit; Light-harvesting photosynthetic bile pigment-protein from the phycobiliprotein complex. (162 aa) |
| | cpcC | Phycocyanin-associated rod linker protein; Rod linker protein, associated with phycocyanin. Linker polypeptides determine the state of aggregation and the location of the disk-shaped phycobiliprotein units within the phycobilisome and modulate their spectroscopic properties in order to mediate a directed and optimal energy transfer. (290 aa) |
| | cpcD | Phycocyanin-associated, rod-terminating linker protein CpcD; Rod linker protein, associated with phycocyanin. Linker polypeptides determine the state of aggregation and the location of the disk-shaped phycobiliprotein units within the phycobilisome and modulate their spectroscopic properties in order to mediate a directed and optimal energy transfer. (80 aa) |
