More | the PSI core complex prepared from cucumber cotyledons contains 80 chlorophylls per reaction center (P700) and eight polypeptides with apparent molecular masses of 65/63, 20,19.5,18.5,17.5,7.6, and 5.8 kDa. The amount of 18.5 kDa polypeptide in the PSI complex affects the activity. When this polypeptide is largely depleted, the complex is almost inactive. The inactivation is due to inhibition of electron transfer from plastocyanin to photooxidized P700. Chemical cross-linking and N-terminal amino acid sequencing experiments indicate that the 18.5-kDa polypeptide is the plastocyanin-docking protein and the psaF gene product | Cucumis sativus |
