    1.97.1.12 | 2,3-dichloronaphthoquinone |
in the mutant menB deletion strain |

710876 |
| 1.97.1.12 | beta-carotene |
cyanobacterial PSI complexes contain 22 molecules of beta-carotene, 17 of which are in all-trans configuration |
710876 |
| 1.97.1.12 | Chlorophyll |
173 chlorophyll molecules in the structure of the entire PSI super-complex. Chl1303 is located in the gap region between the core complex and the light-harvesting complex (LHCI). The Chl1303 position is sufficient for excitation energy transfer from the Lhca14 dimer to the core through chlorophylls 1302 and 1305 |
712479 |
| 1.97.1.12 | Chlorophyll |
photosystem I (PS I) mediates electron-transfer from plastocyanin to ferredoxin via a photochemically active chlorophyll dimer (P700), a monomeric chlorophyll electron acceptor (A0), a phylloquinone (A1), and three [4Fe-4S] clusters (FX/A/B) |
711188 |
| 1.97.1.12 | chlorophyll a |
most abundant cofactor in PSI, role of these molecules in light absorption, charge separation, electron transfer, and biogenesis |
710876 |
| 1.97.1.12 | chlorophyll a' |
one member of the P700 special pair is a chlorophyll a' molecule |
710876 |
| 1.97.1.12 | Ferredoxin |
- |
711483, 744410, 745118 |
| 1.97.1.12 | Ferredoxin |
location of the ferredoxin-binding site in photosystem I, ferredoxin is bound on top of the stromal ridge principally interacting with the extrinsic subunits PsaC and PsaE |
712345 |
| 1.97.1.12 | iron-sulfur centre |
a PSI complex contains 12 iron atoms that constitute 3 [4Fe-4S] clusters |
