ArcAB, also known as the Arc system, is a member of the two-component system family of
bacterial transcriptional regulators and is composed of sensor kinase ArcB and response …

The Arc two-component system is a complex signal transduction system that plays a key role
in regulating energy metabolism at the level of transcription in bacteria. This system …

The Arc two-component signal transduction system mediates adaptive responses of
Escherichia coli to changing respiratory conditions of growth. Under anaerobic conditions …

Overflow metabolism in the form of aerobic acetate excretion by Escherichia coli is an
important physiological characteristic of this common industrial microorganism. Although …

The alternative sigma factor RpoS responds to multiple stresses and activates a large
number of genes that allow bacteria to adapt to changing environments. The accumulation …

The general stress σ factor σS (RpoS) in Escherichia coli is controlled at the levels of
transcription, translation, and proteolysis. Here we demonstrate that the phosphorylated …

The ArcB/ArcA two-component signal transduction system of Escherichia coli regulates gene
expression in response to the redox conditions of growth. Over the years, genetic screens …

Motivation: Transcription regulatory protein factors often bind DNA as homo-dimers or hetero-
dimers. Thus they recognize structured DNA motifs that are inverted or direct repeats or …

Determining how facultative anaerobic organisms sense and direct cellular responses to
electron acceptor availability has been a subject of intense study. However, even in the …

In Escherichia coli, changes in redox condition of growth are sensed and signaled by the Arc
two-component system. This system consists of ArcB as the membrane-associated sensor …
