Aerobic regulation of the Escherichia coli tonB gene by changes in iron availability and the fur locus.

Journal of bacteriology - 1 May 1990

Postle K

Abstract excerpt

The tonB gene is required for the transport of several different iron-siderophore complexes across the Escherichia coli outer membrane. In this study, transcriptional regulation of the tonB gene was investigated by using three different tonB-lacZ fusions to monitor tonB expression under aerobic conditions and in the presence of a wild-type tonB gene. Prior work by other laboratories suggests that tonB is...
