Influence of DNA topology on expression of the tdc operon in Escherichia coli K-12.

Abstract

TdcB activity expressed from the chromosomal gene and LacZ expression from single-copy tdc-lacZ transcriptional and translational fusions were measured in Escherichia coli strains harboring mutations in the genes encoding DNA gyrase, topoisomerase I and the HU protein. The pattern of tdc operon expression in these mutants suggests that relaxation of supercoiled DNA enhances tdc transcription in vivo.
