Escherichia coli σ70 promoters allow expression rate control at the cellular level in genome-integrated expression systems

open access: yesMicrobial Cell Factories, 2020
Background The genome-integrated T7 expression system offers significant advantages, in terms of productivity and product quality, even when expressing the gene of interest (GOI) from a single copy.

Organization of aerobactin, hemolysin, and antibacterial resistance genes in lactose negative Escherichia coli strains of serotype O4 isolated from children with dhiarrea [PDF]

open access: yes, 1992
Epidemiologically related, non-lactose-fermenting (NLF) Escherichia coli strains of serotype O4 have been isolated at a high frequency from children with diarrhea in Somalia (M. Nicoletti, F. Superti, C. Conti, A. Calconi, and C. Zagaglia, J.

Kinetic approaches to lactose operon induction and bimodality

open access: yes, 2013
The quasi-equilibrium approximation is acceptable when molecular interactions are fast enough compared to circuit dynamics, but is no longer allowed when cellular activities are governed by rare events.

Transient repression of the lac operon — the effect of a lac promoter deletion [PDF]

open access: yesFEBS Letters, 1970
Experiments have been done to show whether the lac promoter delection L1, which partly alleviates catabolite repression, also affects transient repression of lac. In stain L1/F′M15 all of the β‐galactosidase is synthesized from a chromosomal gene cis to L1, whereas 98% of the thiogalactosidase transacetylase is synthesized from an episomal gene cis to ...

Insights into the Geobacillus stearothermophilus species based on phylogenomic principles

open access: yesBMC Microbiology, 2017
Background The genus Geobacillus comprises bacteria that are Gram positive, thermophilic spore-formers, which are found in a variety of environments from hot-springs, cool soils, to food manufacturing plants, including dairy manufacturing plants. Despite

Single-cell protein dynamics reproduce universal fluctuations in cell populations

open access: yes, 2015
Protein variability in single cells has been studied extensively in populations, but little is known about temporal protein fluctuations in a single cell over extended times.
