In Escherichia coli, NusG suppresses pausing and increases elongation rate, enhances termination by E. coli rho and phage HK022 Nun protein, and promotes antitermination by lambdaN and in ribosomal RNA operons. We report NMR studies that suggest that E. coli NusG consists of two largely independent N- and C-terminal structural domains, NTD and CTD, respectively. Based on tests of the functions of the NTD and CTD and variants of NusG in vivo and in vitro, we find that NTD alone is sufficient to suppress pausing and enhance transcript elongation in vitro. However, neither domain alone can enhance rho-dependent termination or support antitermination, indicating that interactions of both domains with ECs are required for these processes. We propose that the two domains of NusG mediate distinct interactions with ECs: the NTD interacts with RNA polymerase and the CTD interacts with rho and other regulators, providing NusG with different combinations of interactions to effect different regulatory outcomes.","is_dataset_classified":null,"base_score":5.262690188904886,"endowment":5.262690188904886,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"19500594","pmcid":"PMC2763281","openalex_id":"https://openalex.org/W2115880738","authors":[],"funders":[{"funder_name":"NIGMS NIH HHS","grant_id":"GM38660","title":null},{"funder_name":"NIGMS NIH HHS","grant_id":"R01 GM037219","title":null},{"funder_name":"NIGMS NIH HHS","grant_id":"R56 GM037219","title":null},{"funder_name":"NIGMS NIH HHS","grant_id":"GM037219","title":null},{"funder_name":"NIGMS NIH HHS","grant_id":"R01 GM038660","title":null},{"funder_name":"NIGMS NIH HHS","grant_id":"R37 GM038660","title":null}],"total_grants":6,"fwci":8.4031,"citation_percentile":0.98098565,"influential_citations":0,"citation_trend":[{"year":2012,"count":14},{"year":2013,"count":8},{"year":2014,"count":9},{"year":2015,"count":13},{"year":2016,"count":12},{"year":2017,"count":13},{"year":2018,"count":15},{"year":2019,"count":13},{"year":2020,"count":14},{"year":2021,"count":16},{"year":2022,"count":11},{"year":2023,"count":6},{"year":2024,"count":8},{"year":2025,"count":4},{"year":2026,"count":1}],"oa_status":"closed","license":"https://www.elsevier.com/tdm/userlicense/1.0/","oa_locations":[{"url":"https://api.elsevier.com/content/article/PII:S002228360900672X?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S002228360900672X?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.jmb.2009.05.078","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/19500594","host_type":"repository"},{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/2763281","host_type":"repository"}],"fields_of_study":["Bacterial Genetics and Biotechnology","RNA and protein synthesis mechanisms","DNA and Nucleic Acid Chemistry"],"mesh_terms":["Escherichia coli","Genes, Dominant","Genes, Lethal","Peptide Elongation Factors","Protein Conformation","Rho Factor","DNA-Directed RNA Polymerases","Terminator Regions, Genetic","Transcription Factors","Transcription, Genetic","Protein Structure, Tertiary","Escherichia coli Proteins"],"keywords":["Antitermination","RNA polymerase","Biology","RNA","Transcription (linguistics)","Polymerase","Elongation factor","Cell biology","DNA","Ribosomal RNA","Biophysics","Biochemistry","Ribosome","Gene"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[{"name":"pdb"}],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-12T07:06:07.700086Z","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":[]}
