Escherichia coli cells with increased levels of DnaA and deficient in recombinational repair have decreased viability

, 2003
The dnaA operon of Escherichia coli contains the genes dnaA, dnaN, and recF encoding DnaA, clamp of DNA polymerase III holoenzyme, and RecF. When the DnaA concentration is raised, an increase in the number of DNA replication initiation events but a ...

Intrinsic bent DNA sites in the chromosomal replication origin of Xylella fastidiosa 9a5c

Brazilian Journal of Medical and Biological Research, 2008
The features of the nucleotide sequences in both replication and promoter regions have been investigated in many organisms. Intrinsically bent DNA sites associated with transcription have been described in several prokaryotic organisms.

Autoregulation of the DNA replication gene dnaA in E. coli K-12.

, 1985
The dnaA gene in E. coli K-12 is required for the initiation of DNA replication. Although the specific function of the dnaA protein is unknown, it has been suggested that it is a regulator of the frequency of initiation.

Effect of DnaA protein on lacZ fusion and Characterization of nrdAB Promoter

, 2006
DnaA is known to be the most important protein involved in the initiation of DNA replication in bacteria. It is also found to be involved in transcription regulation. It is well known that DnaA binds to the DnaA boxes.

The physiological role and proteolytic regulation of DnaA in Caulobacter crescentus chromosome replication /

, 2004
Caulobacter crescentus is an asymmetrically dividing bacterium whose progeny differ in their ability to initiate chromosome replication. The stalked cell can initiate replication, whereas the motile swarmer cell must differentiate into a stalked cell ...
