What makes the lac-pathway switch: identifying the fluctuations that trigger phenotype switching in gene regulatory systems [PDF]

open access: yes, 2014
Multistable gene regulatory systems sustain different levels of gene expression under identical external conditions. Such multistability is used to encode phenotypic states in processes including nutrient uptake and persistence in bacteria, fate ...

Allelic expression mapping across cellular lineages to establish impact of non‐coding SNPs

open access: yesMolecular Systems Biology, 2014
Most complex disease‐associated genetic variants are located in non‐coding regions and are therefore thought to be regulatory in nature. Association mapping of differential allelic expression (AE) is a powerful method to identify SNPs with direct cis ...

CrgA Protein Represses AlkB2 Monooxygenase and Regulates the Degradation of Medium-to-Long-Chain n-Alkanes in Pseudomonas aeruginosa SJTD-1

open access: yesFrontiers in Microbiology, 2019
AlkB monooxygenases in bacteria are responsible for the hydroxylation of medium- and long-chain n-alkanes. In this study, one CrgA protein of Pseudomonas aeruginosa SJTD-1, a member of LysR family, was proved to regulate AlkB2 monooxygenase and the ...

Crystallization and preliminary crystallographic analysis of dUTPase from the helper phage Φ11 of Staphylococcus aureus [PDF]

open access: yes, 2011
Staphylococcus aureus superantigen-carrying pathogenicity islands (SaPIs) have a determinant role in spreading virulence genes among bacterial populations that constitute a major health hazard.

The GbsR Family of Transcriptional Regulators: Functional Characterization of the OpuAR Repressor

open access: yesFrontiers in Microbiology, 2018
Accumulation of compatible solutes is a common stress response of microorganisms challenged by high osmolarity; it can be achieved either through synthesis or import.

A 314-bp SINE insertion in the ZNF2 promoter region may act as a repressor related to regulation of fat deposition in pigs

open access: yesJournal of Integrative Agriculture, 2023
Retrotransposons, a type of DNA fragment that can mobilize itself on genome, can generate genetic variations and develop for molecular markers based on the insertion polymorphism.

Accurate prediction of gene feedback circuit behavior from component properties [PDF]

open access: yes, 2007
A basic assumption underlying synthetic biology is that analysis of genetic circuit elements, such as regulatory proteins and promoters, can be used to understand and predict the behavior of circuits containing those elements. To test this assumption, we

Lac repressor at last [PDF]

open access: yesStructure, 1996
Crystal and cocrystal structures of the LacI and PurR repressors reveal a novel use of hinge alpha helices which bind in the minor groove of the operator and mediate transmission of the allosteric signals that modulate DNA-binding activity.

Isolating intrinsic noise sources in a stochastic genetic switch [PDF]

open access: yes, 2011
The stochastic mutual repressor model is analysed using perturbation methods. This simple model of a gene circuit consists of two genes and three promotor states. Either of the two protein products can dimerize, forming a repressor molecule that binds to
