We show that efficient electron transfer from both plastocyanin and cytochrome c6 to PSI depends on PsaF. A remarkable feature of the PSI complex of C. reinhardtii is that both plastocyanin and cytochrome c6 reduce P700+ with first-order kinetics and a half-time of 3 micros, which is unique among photosynthetic organisms examined.","is_dataset_classified":null,"base_score":4.844187086458591,"endowment":4.844187086458591,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"9174349","pmcid":null,"openalex_id":"https://openalex.org/W2158149880","authors":[],"funders":[],"total_grants":0,"fwci":1.7729,"citation_percentile":0.85790569,"influential_citations":0,"citation_trend":[{"year":2012,"count":3},{"year":2013,"count":1},{"year":2014,"count":1},{"year":2015,"count":2},{"year":2016,"count":1},{"year":2017,"count":5},{"year":2018,"count":2},{"year":2019,"count":2},{"year":2020,"count":4},{"year":2021,"count":6},{"year":2022,"count":4},{"year":2023,"count":2},{"year":2024,"count":3},{"year":2025,"count":7},{"year":2026,"count":2}],"oa_status":"closed","license":null,"oa_locations":[{"url":"https://pubs.acs.org/doi/pdf/10.1021/bi970082c","host_type":"publisher"},{"url":"https://doi.org/10.1021/bi970082c","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/9174349","host_type":"repository"}],"fields_of_study":["Photosynthetic Processes and Mechanisms","Photoreceptor and optogenetics research","Spectroscopy and Quantum Chemical Studies","Animals","Chlamydomonas reinhardtii","Cross-Linking Reagents","Cytochromes","Cytochromes f","Electron Transport","Membrane Proteins","Mutation","Oxidation-Reduction","Photosynthetic Reaction Center Complex Proteins","Photosystem I Protein Complex","Plastocyanin","Protozoan Proteins"],"mesh_terms":["Animals","Cross-Linking Reagents","Cytochromes","Electron Transport","Membrane Proteins","Mutation","Oxidation-Reduction","Plastocyanin","Protozoan Proteins","Chlamydomonas reinhardtii","Photosynthetic Reaction Center Complex Proteins","Photosystem I Protein Complex","Cytochromes f"],"keywords":["Plastocyanin","Chlamydomonas reinhardtii","Photosystem I","P700","Cytochrome b6f complex","Chemistry","Cytochrome f","Electron transfer","DCMU","Cytochrome","Photosystem II","Photochemistry","Photosynthesis","Mutant","Biochemistry"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-29T19:53:02.767908Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
