An open reading frame upstream from the nifH gene of Klebsiella pneumoniae [PDF]

open access: yes, 1983
An open reading frame upstream from nifHDK operon of Klebsiella pneumoniae had been described. The orientation of this open reading frame is opposite to that of nifHDK and sequence homology was found between the open reading frame promoter and the ...

Transcription of the lac Operon of Escherichia coli

open access: yesJournal 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

Antibiotic Resistance: A Genetic and Physiological Perspective

open access: yesMedComm, Volume 6, Issue 11, November 2025.
The development of resistance to antimicrobials and their historical progression are depicted in this graphic. It draws attention to important biochemical, physiological, and genetic factors that contribute to AMR, such as the transmission of genes, the development of biofilms, and the inactivation of antibiotics.

Bacteriophage Mu d1(Apr lac) generates vir-lac operon fusions in Shigella flexneri 2a [PDF]

open access: yesInfection and Immunity, 1984
Previous studies have demonstrated that expression of virulence in Shigella spp. is controlled by growth temperature. To study the regulation of virulence (vir) genes, we set out to develop a rapid, easily-assayed phenotype with which to measure expression of virulence.

Pre‐dispositions and epigenetic inheritance in the Escherichia coli lactose operon bistable switch

open access: yesMolecular Systems Biology, 2010
The lactose operon regulation in Escherichia coli is a primary model of phenotypic switching, reminiscent of cell fate determination in higher organisms.

Subpopulations of sensorless bacteria drive fitness in fluctuating environments.

open access: yesPLoS Biology, 2020
Populations of bacteria often undergo a lag in growth when switching conditions. Because growth lags can be large compared to typical doubling times, variations in growth lag are an important but often overlooked component of bacterial fitness in ...

Synthetic biology—putting engineering into biology [PDF]

open access: yes, 2006
Synthetic biology is interpreted as the engineering-driven building of increasingly complex biological entities for novel applications. Encouraged by progress in the design of artificial gene networks, de novo DNA synthesis and protein engineering, we ...

Novel Insights Into the Struggle Against Biofilm: The PsyOmp38 Protein From the Antarctic Marine Bacterium Psychrobacter sp. TAE2020

open access: yesMicrobial Biotechnology, Volume 18, Issue 10, October 2025.
The protein PsyOmp38 inhibits biofilm formation and disrupts the mature biofilm of Staphylococcus epidermidis. The use of this antibiofilm protein in combination with vancomycin increases the efficacy of the antibiotic, reducing its MBEC on S. epidermidis. Furthermore, PDMS coated with PsyOmp38 prevents S.

Membrane topology of the ArsB protein, the membrane subunit of an anion-translocating ATPase [PDF]

open access: yes, 1992
The ars operon of the conjugative R-factor R773 encodes an oxyanion pump that catalyzes extrusion of arsenicals from cells of Escherichia coli. The oxyanion translocation ATPase is composed of two polypeptides, the catalytic ArsA protein and the ...

Phenotypic Variation and Bistable Switching in Bacteria [PDF]

open access: yes, 2008
Microbial research generally focuses on clonal populations. However, bacterial cells with identical genotypes frequently display different phenotypes under identical conditions.
