▪ Abstract Most prokaryotic signal-transduction systems and a few eukaryotic pathways use
phosphotransfer schemes involving two conserved components, a histidine protein kinase …

This review will cover the developments in the chemistry of phenanthroline-based ligands in
the last 10–15 years. 1, 10-Phenanthroline (phen) is a classic ligand in coordination …

ABSTRACT The Escherichia coli OmpR/EnvZ two-component regulatory system, which
senses environmental osmolarity, also regulates biofilm formation. Up mutations in the …

EnvZ, a histidine kinase/phosphatase inEscherichia coli, responds to the osmolarity
changes in the medium by regulating the phosphorylation state of the transcription factor …

PhoB is a signal transduction response regulator that activates nearly 40 genes in
phosphate depletion conditions in E. coli and closely related bacteria. The structure of the …

Curli fibers could be described as a virulence factor able to confer adherence properties to
both abiotic and eukaryotic surfaces. The ability to adapt rapidly to changing environmental …

In Escherichia coli, the two-component Cpx system comprising the CpxA sensor kinase and
the CpxR response regulator modulates gene expression in response to a variety of …

Two-component regulatory systems represent the major paradigm for signal transduction in
prokaryotes. The simplest systems are composed of a sensor kinase and a response …

Related organisms typically respond to a given cue by altering the level or activity of
orthologous transcription factors, which, paradoxically, often regulate expression of distinct …

Response regulators are the output component of two-component regulatory systems, the
predominant form of signal transduction systems utilized by prokaryotes. The majority of …
