To systematically mutagenise the genome of the Gram-positive bacterium Streptomyces coelicolor A3(2), we have employed high-throughput shuttle transposon mutagenesis of a cosmid library prepared in Escherichia coli. The location of transposon insertions is determined using automated procedures for cosmid isolation and DNA sequencing. However, a major bottleneck was the subsequent analysis of DNA sequence files. To overcome this limitation, a software application, Transposon Express, was written to allow the rapid location of transposon insertions in a sequenced genome (available at http://www.swan.ac.uk/genetics/dyson/InstallTE). Transposon Express determines the identity both of a disrupted open reading frame (ORF), and the short target site duplication created by transposition. Transposon Express also reports the orientation of the transposon and can therefore predict transcriptional coupling between an upstream promoter and a promoter-less reporter gene carried by the transposon. Analysis of a large dataset of independent insertions created using a Tn5-based transposon revealed an insertional preference for GC-rich streptomycete DNA compared to E.coli vector DNA. In addition to demonstrating the value of Transposon Express as a generic tool supporting genome-wide transposon mutagenesis programs, these data provide insight into target site selection by Tn5.","is_dataset_classified":null,"base_score":4.007333185232471,"endowment":4.007333185232471,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"15308758","pmcid":"PMC514396","openalex_id":"https://openalex.org/W2075978325","authors":[],"funders":[{"funder_name":"Biotechnology and Biological Sciences Research Council","grant_id":"EGH18395","title":null}],"total_grants":1,"fwci":2.3947,"citation_percentile":0.88430208,"influential_citations":0,"citation_trend":[{"year":2012,"count":3},{"year":2013,"count":4},{"year":2014,"count":1},{"year":2015,"count":1},{"year":2016,"count":2},{"year":2017,"count":4},{"year":2018,"count":2},{"year":2020,"count":2},{"year":2021,"count":1},{"year":2023,"count":1},{"year":2024,"count":3},{"year":2025,"count":2}],"oa_status":"bronze","license":null,"oa_locations":[{"url":"https://academic.oup.com/nar/article-pdf/32/14/e113/4108626/gnh112.pdf","host_type":"journal"},{"url":"https://academic.oup.com/nar/article-pdf/32/14/e113/4108626/gnh112.pdf","host_type":"publisher"},{"url":"http://academic.oup.com/nar/article-pdf/32/14/e113/4108626/gnh112.pdf","host_type":"publisher"},{"url":"https://doi.org/10.1093/nar/gnh112","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/15308758","host_type":"repository"},{"url":"http://europepmc.org/pmc/articles/PMC514396","host_type":"repository"},{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/514396","host_type":"repository"},{"url":"https://strathprints.strath.ac.uk/38109/","host_type":"repository"}],"fields_of_study":["Bacterial Genetics and Biotechnology","RNA and protein synthesis mechanisms","Bacteriophages and microbial interactions","Computational Biology","Consensus Sequence","Cosmids","DNA Transposable Elements","DNA, Bacterial","Escherichia coli","GC Rich Sequence","Gene Library","Genetic Vectors","Genome, Bacterial","Genomics","Molecular Sequence Data","Mutagenesis, Insertional","Sequence Analysis, DNA","Software","Streptomyces"],"mesh_terms":["Cosmids","DNA Transposable Elements","DNA, Bacterial","Escherichia coli","Genetic Vectors","Molecular Sequence Data","Software","Streptomyces","Gene Library","Mutagenesis, Insertional","Consensus Sequence","Genome, Bacterial","Sequence Analysis, DNA","Computational Biology","GC Rich Sequence","Genomics"],"keywords":["Transposable element","Transposon mutagenesis","Biology","Sleeping Beauty transposon system","Genetics","Tn3 transposon","Insertional mutagenesis","Genome","Cosmid","Genomic library","Mutagenesis","Transposase","Transposition (logic)","DNA","Mutation","Gene"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Quality Education"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[{"name":"gen"}],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-29T17:37:56.341246Z","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":[]}
