    • Promoter activity of ORF-less gene cassettes isolated from the oral metagenome 

      Tansirichaiya, Supathep; Mullany, Peter; Roberts, Adam P. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-10)
      Integrons are genetic elements consisting of a functional platform for recombination and expression of gene cassettes (GCs). GCs usually carry promoter-less open reading frames (ORFs), encoding proteins with various functions including antibiotic resistance. The transcription of GCs relies mainly on a cassette promoter (P<sub>C</sub>), located upstream of an array of GCs. Some integron GCs, called ...
