CadC-mediated activation of the cadBA promoter in Escherichia coli [PDF]
, 2005 The transcriptional activator CadC in Escherichia coli, a member of the ToxR-like proteins, activates transcription of the cadBA operon encoding the lysine decarboxylase CadA and the lysine-cadaverine antiporter CadB. cadBA is induced under conditions of

Transcriptional downregulation of agr expression in Staphylococcus aureus during growth in human serum can be overcome by constitutively active mutant forms of the sensor kinase AgrC [PDF]
, 2013 The temporal and cell density-dependent regulation of expression of virtually all the Staphylococcus aureus virulon is under the control of the agr (accessory gene regulatory) operon.

Transcription of the lac Operon of Escherichia coli
Journal of Biological Chemistry, 1974 The effects of induction and of transient and catabolite repression on lac-specific RNA in cells of Escherichia coli were investigated. The rate of lac-specific RNA synthesis increases linearly for 3 min after induction and then becomes constant. The accumulation of RNA complementary to the promoter proximal lac Z gene begins before accumulation of RNA

Protein Science, Volume 35, Issue 6, June 2026.Abstract Zinc finger proteins are essential for the proper functioning of eukaryotic organisms, while their artificial variants can be used in cancer therapy or gene editing via their specific DNA recognition. Zn(II) binding is indispensable for the structural integrity of zinc fingers.

Pensar con y a partir del operón
Revista Colombiana de Filosofía de la CienciaEste artículo sostiene que el operón lac propuesto por François Jacob y Jacques Monod en 1961 superó los campos de la cinética enzimática y la genética bacteriana en los que se estableció originalmente porque impulsó una metodología de análisis, el ...

Relatively slow stochastic gene-state switching in the presence of positive feedback significantly broadens the region of bimodality through stabilizing the uninduced phenotypic state. [PDF]
PLoS Computational Biology, 2018 Within an isogenic population, even in the same extracellular environment, individual cells can exhibit various phenotypic states. The exact role of stochastic gene-state switching regulating the transition among these phenotypic states in a single cell ...

Plasmid copy number underlies adaptive mutability in bacteria. [PDF]
, 2014 The origin of mutations under selection has been intensively studied using the Cairns-Foster system, in which cells of an Escherichia coli lac mutant are plated on lactose and give rise to 100 Lac+ revertants over several days. These revertants have been

Advanced Science, Volume 13, Issue 23, 23 April 2026.Dimethylsulfoniopropionate (DMSP) is a major marine organosulfur compound central to climate‐relevant dimethyl sulfide (DMS) production. In Halomonas sp. D47, DMSP catabolism is revealed to be coordinated by two transcriptional regulators, AcuR and AcuZ, which control gene expression by sensing DMSP and its metabolites.
