Termination efficiency at both of these sites is enhanced by the E. coli nusA protein, giving final efficiencies of termination in vitro comparable to those estimated in vivo. Transcripts terminated in the presence of nusA protein are all released from the RNA polymerase complex, indicating that a complete termination reaction is involved, rather than simply induction of a long pause at the terminator. The termination factor activity of the nusA protein does not depend on the presence of rho protein and is not detectably enhanced by that factor. Thus, the nusA protein appears to play a pleiotropic role in E. coli transcription, serving as an antitermination factor, RNA polymerase subunit and true termination factor for some terminator sites.","is_dataset_classified":null,"base_score":4.820281565605037,"endowment":4.820281565605037,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"2821282","pmcid":null,"openalex_id":"https://openalex.org/W2003778374","authors":[],"funders":[{"funder_name":"NIGMS NIH HHS","grant_id":"GM12010","title":null},{"funder_name":"NIGMS NIH HHS","grant_id":"GM07232","title":null}],"total_grants":2,"fwci":5.7797,"citation_percentile":0.96285915,"influential_citations":0,"citation_trend":[{"year":2012,"count":2},{"year":2013,"count":2},{"year":2014,"count":1},{"year":2015,"count":1},{"year":2016,"count":6},{"year":2018,"count":2},{"year":2019,"count":3},{"year":2021,"count":3},{"year":2022,"count":4},{"year":2023,"count":3},{"year":2024,"count":2},{"year":2026,"count":3}],"oa_status":"closed","license":"https://www.elsevier.com/tdm/userlicense/1.0/","oa_locations":[{"url":"https://api.elsevier.com/content/article/PII:0022283687904864?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:0022283687904864?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/0022-2836(87)90486-4","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/2821282","host_type":"repository"}],"fields_of_study":["Bacterial Genetics and Biotechnology","RNA and protein synthesis mechanisms","Bacteriophages and microbial interactions","Bacterial Proteins","Bacteriophage lambda","DNA, Viral","Escherichia coli","Genes, Regulator","Plasmids","Templates, Genetic","Terminator Regions, Genetic","Transcription, Genetic"],"mesh_terms":["Bacterial Proteins","DNA, Viral","Escherichia coli","Genes, Regulator","Bacteriophage lambda","Plasmids","Templates, Genetic","Terminator Regions, Genetic","Transcription, Genetic"],"keywords":["Antitermination","Terminator (solar)","Termination factor","RNA polymerase","Escherichia coli","Biology","Transcription (linguistics)","Bacteriophage","Molecular biology","Bacterial transcription","Operon","Protein subunit","Cell biology","Chemistry","Genetics","Gene","Physics"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-05T19:38:44.926774Z","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":[]}
