Modulation of tyrT promoter activity by template supercoiling in vivo.
We have found that initiation of RNA synthesis at the tyrT promoter of Escherichia coli can be stimulated on a plasmid by a factor of 4-6 by elevation of DNA supercoiling in vivo. Increased unconstrained plasmid supercoiling was achieved by inserting the tyrT promoter upstream of the tetracycline re...
