Stochastic switching induced adaptation in a starved Escherichia coli population. [PDF]

open access: yesPLoS ONE, 2011
Population adaptation can be determined by stochastic switching in living cells. To examine how stochastic switching contributes to the fate decision for a population under severe stress, we constructed an Escherichia coli strain crucially dependent on ...

Molecular Basis for the Ribosome Functioning as an L-Tryptophan Sensor

open access: yesCell Reports, 2014
Elevated levels of the free amino acid L-tryptophan (L-Trp) trigger expression of the tryptophanase tnaCAB operon in E. coli. Activation depends on tryptophan-dependent ribosomal stalling during translation of the upstream TnaC peptide.

Morphological development and cytochrome c oxidase activity in Streptomyces lividans are dependent on the action of a copper bound Sco protein [PDF]

open access: yes, 2013
Copper has an important role in the life cycle of many streptomycetes, stimulating the developmental switch between vegetative mycelium and aerial hyphae concomitant with the production of antibiotics.

The Bacillus cereus GerN and GerT protein homologs have distinct roles in spore germination and outgrowth, respectively [PDF]

open access: yes, 2008
The GerT protein of Bacillus cereus shares 74% amino acid identity with its homolog GerN. The latter is a Na+/H+-K+ 19 antiporter that is required for normal spore germination in inosine.

TRP and Rhodopsin Transport Depends on Dual XPORT ER Chaperones Encoded by an Operon

open access: yesCell Reports, 2015
TRP channels and G protein-coupled receptors (GPCRs) play critical roles in sensory reception. However, the identities of the chaperones that assist GPCRs in translocating from the endoplasmic reticulum (ER) are limited, and TRP ER chaperones are ...

From DNA sequence to application: possibilities and complications [PDF]

open access: yes, 1999
The development of sophisticated genetic tools during the past 15 years have facilitated a tremendous increase of fundamental and application-oriented knowledge of lactic acid bacteria (LAB) and their bacteriophages.

Repetitive Short-Term Stimuli Imposed in Poor Mixing Zones Induce Long-Term Adaptation of E. coli Cultures in Large-Scale Bioreactors: Experimental Evidence and Mathematical Model

open access: yesFrontiers in Microbiology, 2017
Rapidly changing concentrations of substrates frequently occur during large-scale microbial cultivations. These changing conditions, caused by large mixing times, result in a heterogeneous population distribution.

Metabolite-dependent regulation of gene expression in trypanosoma brucei [PDF]

open access: yes, 2013
Mechanisms regulating gene expression in trypanosomatid protozoa differ significantly from those in other eukaryotes. Transcription of the genome appears to be more or less constitutive with the polyadenylation and trans-splicing of large polycistronic ...

Controlled overproduction of proteins by lactic acid bacteria [PDF]

open access: yes, 1997
Lactic acid bacteria are widely used in industrial food fermentations, contributing to flavour, texture and preservation of the fermented products. Here we describe recent advances in the development of controlled gene expression systems, which allow the

Roles of transcriptional and translational control mechanisms in regulation of ribosomal protein synthesis in Escherichia coli [PDF]

open access: yes, 2017
Bacterial ribosome biogenesis is tightly regulated to match nutritional conditions and to prevent formation of defective ribosomal particles. InEscherichia coli, most ribosomal protein (r-protein) synthesis is coordinated with rRNA synthesis by a ...
