(Submitter supplied) Caulobacter species are dimorphic Gram-negative bacteria that inhabit diverse terrestrial and aquatic ecosystems. A suite of molecular sensory systems enables these microbes to control growth, development, and reproduction in response to levels of essential elements, including carbon, nitrogen, and phosphorus. Although the enhancer binding protein NtrC and its cognate sensor histidine kinase NtrB are well-established regulators of bacterial nitrogen assimilation, their precise functions in Caulobacter metabolism and cell development remained largely undefined. more...

(Submitter supplied) We sought to define the transcriptional regulon of the ChvI response regulator in Caulobacter crescentus. This study compares gene expression between ∆chvI cells and cells overexpressing the constitutively-active chvI(D52E) mutant. Our work provides a global view of the genes directly and indirectly regulated by the ChvGI two-component system in C. crescentus.

(Submitter supplied) The Bradyrhizobium japonicum NtrC regulatory protein influences gene expression in response to changes in intracellular nitrogen status. Under conditions of low nitrogen, phosphorylation of NtrC results in up-regulation of a number of genes involved in nitrogen metabolism and nitrogen acquisition. To better define the exact nature of NtrC’s influence on gene expression, a ntrC mutation was created in B. more...

(Submitter supplied) Nitrogen is one of the major nutrients limiting microbial productivity in the ocean, and as a result marine microorganisms have evolved specialized systems for responding to nitrogen stress. The highly abundant alphaproteobacterium Candidatus Pelagibacter ubique lacks the canonical GlnB, GlnD, and NtrB/NtrC genes for regulating nitrogen assimilation. A survey of 127 Alphaproteobacteria genomes found these genes to be highly represented in free-living and pathogenic organisms with large genomes and only missing in a subset of obligate intracellular organisms and other SAR11 strains. more...

(Submitter supplied) Potassium (K+) is an essential physiological element determining membrane potential, intracellular pH, osmotic/turgor pressure, and protein synthesis in cells. Nevertheless, K+ homeostasis remains poorly studied in bacteria. Here we describe the regulation of potassium uptake systems in the oligotrophic -proteobacterium Caulobacter crescentus known as a model for asymmetric cell division. We show that C. more...

(Submitter supplied) Potassium (K+) is an essential physiological element determining membrane potential, intracellular pH, osmotic/turgor pressure, and protein synthesis in cells. Here we describe the regulation of potassium uptake systems in the oligotrophic alpha-proteobacterium Caulobacter crescentus known as a model for asymmetric cell division. We show that C. crescentus can grow in concentrations from the micromolar to the millimolar range by mainly using two K+ transporters to maintain potassium homeostasis, the low affinity Kup and the high affinity Kdp uptake systems. more...

(Submitter supplied) A multi-layered structure known as the cell envelope separates the controlled interior of Gram-negative bacteria from a fluctuating physical and chemical environment. Transcription of genes that determine cell envelope structure and function is commonly controlled by a class of environmental regulators known as two-component signal transduction systems (TCS), which are comprised of 1) sensor histidine kinases and 2) response regulators. more...
