The Escherichia coli flagellar transcriptional activator flhD regulates cell division through induction of the acid response gene cadA.
نویسندگان
چکیده
FlhD is a positive regulator of cadA. A mutant with a transposon-mediated lacZ fusion to cadA exhibited a cell division phenotype similar to that of the flhD mutant and had FlhD-dependent beta-galactosidase activity. Under different growth conditions, the cell division rate correlated with the level of expression of cadA.

A regulator of the flagellar regulon of Escherichia coli, flhD, also affects cell division.
The role of an activator of flagellar transcription in Escherichia coli, flhD, was investigated in the regulation of cell division. When grown in tryptone broth, flhD mutant cells divided exponentially until they reached a cell density of 2.5 x 10(9) cells per ml. Wild-type cells and flhC mutant cells divided exponentially until they reached a cell density of 4 x 10(7) cells per ml. flhD mutant...
متن کاملThe C-terminal region of the alpha subunit of Escherichia coli RNA polymerase is required for transcriptional activation of the flagellar level II operons by the FlhD/FlhC complex.
A number of transcription activators have been found to activate transcription via protein-protein contact between RNA polymerase alpha subunits and transcription factors; they are classified as class I factors. In this report, we demonstrate that the FlhD/FlhC complex, a transcription activator of the Escherichia coli flagellar regulon, requires the C-terminal domain of the RNA polymerase alph...
متن کاملBinding and transcriptional activation of non-flagellar genes by the Escherichia coli flagellar master regulator FlhD2C2.
The gene hierarchy directing biogenesis of peritrichous flagella on the surface of Escherichia coli and other enterobacteria is controlled by the heterotetrameric master transcriptional regulator FlhD(2)C(2). To assess the extent to which FlhD(2)C(2) directly activates promoters of a wider regulon, a computational screen of the E. coli genome was used to search for gene-proximal DNA sequences s...
متن کاملStructural insight of a concentration-dependent mechanism by which YdiV inhibits Escherichia coli flagellum biogenesis and motility
YdiV is a negative regulator of cell motility. It interacts with FlhD(4)C(2) complex, a product of flagellar master operon, which works as the transcription activator of all other flagellar operons. Here, we report the crystal structures of YdiV and YdiV(2)-FlhD(2) complex at 1.9 Å and 2.9 Å resolutions, respectively. Interestingly, YdiV formed multiple types of complexes with FlhD(4)C(2). YdiV...
متن کاملIncreased motility of Escherichia coli by insertion sequence element integration into the regulatory region of the flhD operon.
The flhD operon is the master operon of the flagellar regulon and a global regulator of metabolism. The genome sequence of the Escherichia coli K-12 strain MG1655 contained an IS1 insertion sequence element in the regulatory region of the flhD promoter. Another stock of MG1655 was obtained from the E. coli Genetic Stock Center. This stock contained isolates which were poorly motile and had no I...
