The Glutaminase-dependent system confers extreme acid resistance to new species and atypical strains of Brucella [PDF]
, 2017 Neutralophilic bacteria have developed specific mechanisms to cope with the acid stress encountered in environments such as soil, fermented foods, and host compartments. In Escherichia coli, the glutamate decarboxylase (Gad)-dependent system is extremely

Operon and non-operon gene clusters in the C. elegans genome [PDF]
WormBook, 2014 Nearly 15% of the ~20,000 C. elegans genes are contained in operons, multigene clusters controlled by a single promoter. The vast majority of these are of a type where the genes in the cluster are ~100 bp apart and the pre-mRNA is processed by 3' end formation accompanied by trans-splicing.

Detection of Protein–Protein Interactions in Escherichia coli With Single Molecule Sensitivity
Advanced Science, EarlyView.This article describes a regulatory circuit in Escherichia coli able to detect protein–protein interactions with exquisite sensitivity. The interaction between two hybrid proteins fused to Bordetella pertussis adenylate cyclase and its activator calmodulin triggers a potent cyclic AMP signaling cascade.

Sinorhizobium Meliloti, A Bacterium Lacking The Autoinducer-2 (AI-2) Synthase, Responds To AI-2 Supplied By Other Bacteria [PDF]
, 2008 Many bacterial species respond to the quorum-sensing signal autoinducer-2 (AI-2) by regulating different niche-specific genes. Here, we show that Sinorhizobium meliloti, a plant symbiont lacking the gene for the AI-2 synthase, while not capable of ...

Advanced Science, EarlyView.When a master transcription factor (TF) is lost, bacteria can rapidly rewire gene regulatory networks by co‐opting related regulators. Using experimental evolution in Pseudomonas fluorescens, we show that TF promiscuity (low‐level, non‐cognate binding) provides the raw material for rewiring. Successful co‐option follows a predictable hierarchy governed

N-acetylgalatosamine-mediated regulation of the aga operon by AgaR in Streptococcus pneumoniae
Frontiers in Cellular and Infection Microbiology, 2016 Here, we analyze the transcriptomic response of Streptococcus pneumoniae D39 to N-acetylgalactosamine (NAGa). Transcriptome comparison of S. pneumoniae D39 grown NAGaM17 (0.5% NAGa + M17) to that grown in GM17 (0.5% Glucose + M17) revealed the elevated ...

Regulation of potassium dependent ATPase (kdp) operon of Deinococcus radiodurans. [PDF]
PLoS ONE, 2017 The genome of D. radiodurans harbors genes for structural and regulatory proteins of Kdp ATPase, in an operon pattern, on Mega plasmid 1. Organization of its two-component regulatory genes is unique.

embCAB Sequence Variation Among Ethambutol-Resistant Mycobacterium Tuberculosis Isolates Without embB306 Mutation [PDF]
, 2010 Mechanisms of resistance to ethambutol in Mycobacterium tuberculosis remain inadequately described. Although there is mounting evidence that mutations of codon 306 in embB play a key role, a significant number of phenotypically ethambutol-resistant ...
