The bacterial replication origin BUS promotes nucleobase capture
Genome duplication is essential for the proliferation of cellular life and this process is generally initiated by dedicated replication proteins at chromosome origins.

DnaA is the widely conserved bacterial AAA+ ATPase that functions as both the replication initiator and a transcription factor. In many organisms, DnaA controls expression of its own gene and likely several others during growth and in response to ...

Research on DnaA in the early days
The Escherichia coli chromosome is a circular double helix. DNA polymerase, therefore, cannot use it directly as a template for polymerization until it has first been unwound. The DnaA protein opens the chromosome at a unique and specific site (oriC), which allows the polymerase to begin DNA replication.

Genome duplication is a critical event in the reproduction cycle of every cell. Because all daughter cells must inherit a complete genome, chromosome replication is tightly regulated, with multiple mechanisms focused on controlling when chromosome ...

DnaA-dependent riboswitch for transcription attenuation
Transcription attenuation has been believed to be controlled by alternative configurations of RNA secondary structures through arresting or releasing the ribosome on the leader RNA molecule in response to limitation or sufficiency of specific amino acid.

Occlusion of RNA Polymerase by Oligomerization of DnaA Protein over the dnaA Promoter of Escherichia coli [PDF]
DnaA protein, the initiator protein for initiation of Escherichia coli chromosomal replication, has been shown to repress its own expression from two dnaA promoters, 1P and 2P. The sequence-specific binding of DnaA protein to the DnaA box, located between the two promoters, results in subsequent oligomerization of DnaA protein.

The initiation of bacterial chromosomal replication is regulated by multiple pathways. To explore novel regulators, we isolated multicopy suppressors for the cold-sensitive hda-185 ΔsfiA(sulA) mutant.
