A transposon (TnC_T7) was developed to partially supply the transcriptional machinery during functional analysis of genomic/metagenomic libraries. This transposon was conceived and constructed to have the ability to integrate randomly into any episomal DNA, allowing the inducible expression of the adjacent DNA regions in both directions. In general, this genetic tool included a kanamycin resistance gene, two bidirectional T7 promoters and the T7RNA polymerase-coding gene, the latter under the regulation of the inducible arabinose promoter (P). The experimental validation confirmed the TnC_T7 potential to be used in functional genomic/metagenomic studies, in order to partially overcome the limitations of the bacterial hosts, which prevent them to recognize most of foreign genes from DNA libraries.
