title: Effect of DNA supercoiling on in vitro transcription from the adenovirus early region 4.
abstract: The effect of DNA supercoiling on in vitro transcription from the early region 4 (E4) promoter of adenovirus type 5 (Ad5) has been investigated by using a cell-free transcription system that maintains supercoiled DNA templates. The supercoiled DNAs yield several-fold higher levels of E4 transcripts and more faithfully reflect the regulation of in vivo transcription than the linear DNAs.
