Homologous recombination is a fundamental biological process. Biochemical
understanding of this process is most advanced for Escherichia coli. At least 25 gene …

Although homologous recombination and DNA repair phenomena in bacteria were initially
extensively studied without regard to any relationship between the two, it is now appreciated …

SUMMARY The RecBCD enzyme of Escherichia coli is a helicase-nuclease that initiates the
repair of double-stranded DNA breaks by homologous recombination. It also degrades …

Defined mutations of acrA or acrB (formerly acrE) genes increased the susceptibility of
Escherichia coli to a range of small inhibitor molecules. Deletion of acrAB increased …

The single-stranded DNA-binding protein (SSB) of Escherichia coli is involved in all aspects
of DNA metabolism: replication, repair, and recombination. In solution, the protein exists as a …

Genes acrAB encode a multidrug efflux pump in Escherichia coli. We have previously
reported that transcription of acrAB is increased under general stress conditions (ie 4 …

Genetic evidence suggests that the RecF, RecO, and RecR (RecFOR) proteins participate in
a common step of DNA recombination and repair, yet the biochemical event requiring …

We have determined that 10Sa RNA (one of the small stable RNAs found in Escherichia
coli) has an interesting structural feature: the 5'end and the 3'end of 10Sa RNA can be …

Nitric oxide (NO) is a poison, and organisms employ diverse systems to protect against its
harmful effects. InEscherichia coli, ygaA encodes a transcription regulator (b2709) …

The Escherichia coli recJ gene product was overproduced using a plasmid that carries the
recJ gene downstream of a strong regulatable promoter and a strong ribosome-binding site …
