E. coli SeqA protein binds oriC in two different methyl-modulated reactions appropriate to its roles in DNA replication initiation and origin sequestration [PDF]

, 1995
The segA gene negatively modulates replication initiation at the E. coil origin, oriC. segA is also essential for sequestration, which acts at oriC and the dnaA promoter to ensure that replication initiation occurs exactly once per chromosome per cell ...

Structural Changes and Transport Properties of YBa2Cu3O7 Locally Modified by a He+ Focused Ion Beam

Advanced Science, EarlyView.
The structure and the electric transport properties of YBa2Cu3O7 modified with 30 keV He+${\rm He}^{+}$ ions depend on the irradiation dose and lateral size of the irradiated area, as shown by low‐temperature resistivity measurements, diffraction with a nanofocused X‐ray beam and atomic force microscopy.

Existing interventions for the management of different types of dysgraphia or specific learning disorder in written expression: a scoping review

BMJ Open
Background Dysgraphia is a specific learning disorder characterised by difficulties in written expression. Identifying and finding remedies for children with this disorder is challenging due to the diverse interventions used in different contexts ...

Long range chromosome organization in Escherichia coli: The position of the replication origin defines the non-structured regions and the Right and Left macrodomains. [PDF]

PLoS Genetics, 2017
The Escherichia coli chromosome is organized into four macrodomains (Ori, Ter, Right and Left) and two non-structured regions. This organization influences the segregation of sister chromatids, the mobility of chromosomal DNA, and the cellular ...

Chelation‐Driven Dual‐Interface Regulation for Long‐Life Aqueous Zn–I2 Batteries

Advanced Science, EarlyView.
Zn2+–TPEN coordination generates TPEN‐derived coordination species (TCC) that contribute to the regulation of both electrode interfaces. At the Zn anode, it creates an interfacial environment with reduced water accessibility that suppresses HER and corrosion while promoting uniform deposition; at the I2 cathode, it captures polyiodide to inhibit ...

Filigree in Istria: From the "brotherhood and unity" to multiculturalism

Etnoantropološki Problemi, 2014
The aim of the paper is a diachronic research of the Albanian minority engaged with filigree production and the relationships (of power) between minorities present today in Istria. The text is motivated by three factors. Firstly because of the prevailing

Host specificity of mollicutes oriC plasmids: functional analysis of replication origin

, 2003
Recently, arti®cial oriC plasmids containing the chromosomal dnaA gene and surrounding DnaA box sequences were obtained for the mollicutes Spiroplasma citri and Mycoplasma pulmonis.

Autonomous Solar Metallurgy for High‐Purity Gold Recovery from Electronic Waste

Advanced Science, EarlyView.
Inspired by microbial strategies for metal uptake and biomineralization, defect‐rich copper sulfide (Cu31S16) functions as a solar metallurgical platform that unifies Au(III) capture, reduction, and self‐separation. The bioinspired design enables ultrafast gold recovery from electronic‐waste leachates and the spontaneous formation of millimeter‐scale ...

Cnu, a Novel oriC-Binding Protein of Escherichia coli

, 2005
We have found, using a newly developed genetic method, a protein (named Cnu, for oriC-binding nucleoid-associated) that binds to a specific 26-base-pair sequence (named cnb) in the origin of replication of Escherichia coli, oriC.

Synthetic Shewanella‐Bacillus Microbial Consortia for Enhanced Metal Oxide Leaching From Spent Lithium‐Ion Batteries Using Brewing Wastewater as Leaching Agent

Advanced Science, EarlyView.
A recycling approach of spent lithium‐ion batteries is developed using brewing wastewater as the leaching agent and an engineering microbial consortium as the biocatalyst. Shewanella oneidensis reduces spent LiNixCoyMn1‐x‐yO2 cathodes via extracellular electron transfer, while Bacillus subtilis removes residual ethanol to eliminate inhibition.
