Post-replicative pairing of sister ter regions in Escherichia coli involves multiple activities of MatP [PDF]

Nature Communications, 2020
Protein, MatP, binds to and delays segregation of the ter region of the bacterial chromosome before cell division. Here, the authors show that MatP displays multiple activities to promote optimal pairing of sister ter regions until cell division.

MatP regulates the coordinated action of topoisomerase IV and MukBEF in chromosome segregation [PDF]

Nature Communications, 2016
MukBEF, the bacterial structural maintenance of chromosomes complex, is known to associate with origins of replication and topoisomerase IV. Here the authors show an association of MukBEF with MatP and replication termination regions, important for ...

A mutation in the MATP gene causes the cream coat colour in the horse [PDF]

Genetics Selection Evolution, 2003
In horses, basic colours such as bay or chestnut may be partially diluted to buckskin and palomino, or extremely diluted to cream, a nearly white colour with pink skin and blue eyes. This dilution is expected to be controlled by one gene and we used both

Standardization of Methodology for Polymorphism Detection in ASIP, MC1R and MATP Genes in Relation to Colour in Horses

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2017
The basic colour in horses, such as black, brown and chestnut is affected by only two genes MC1R and ASIP. Other colours in horses are affected by modifying genes, such as dilution gene MATP.

Ultra-Wideband Multidomain Modulation for Pulse LFM Radar Deception

International Journal of Antennas and Propagation
An ultrawideband multidomain modulation method for pulse linear frequency modulation (LFM) radar deception, leveraging a dynamic Mach–Zehnder modulator (MZM) and fiber delay links, is proposed.

Direct activation of airway sensory C-fibers by SARS-CoV-2 S1 spike protein. [PDF]

Physiol Rep, 2023
We investigated whether the S1 subunit of the β‐CoV spike protein could directly activate sensory C‐fibers. Limited presence of ACE2 or TLR4 in mouse vagal sensory C‐fiber neurons suggests that direct activation doesn't occur via ACE2 or TLR4 binding. Other potential pathways, such as galectin‐3 dependent or TRP channel, warrant further investigation ...

Biomanufacturing Potential of Streamlined Cells. [PDF]

Biotechnol Bioeng
ABSTRACT A series of Escherichia coli streamlined strains was developed by removing the expression of genes encoding extracellular structures and unessential enzymes. The streamlined strains exhibited improved metabolic performance, including lower overflow metabolism and ATP maintenance coefficient, as well as a higher growth rate, compared to their ...

ZapA uses a two-pronged mechanism to facilitate Z ring formation in <i>Escherichia coli</i>. [PDF]

mLife
Abstract The tubulin‐like protein FtsZ assembles into the Z ring that leads to the assembly and activation of the division machinery in most bacteria. ZapA, a widely conserved protein that interacts with FtsZ, plays a pivotal role in organizing FtsZ filaments into a coherent Z ring.

Competitive binding of MatP and topoisomerase IV to the MukB dimerization hinge [PDF]

, 2021
ABSTRACTSMC complexes have ubiquitous roles in chromosome organisation. InEscherichia coli,the interplay between the SMC complex, MukBEF, and matS-bound MatP in the replication termination region, ter, results in depletion of MukBEF from ter, thus promoting chromosome individualisation by directing replichores to separate cell halves.

Differential management of the replication terminus regions of the two Vibrio cholerae chromosomes during cell division. [PDF]

PLoS Genetics, 2014
The replication terminus region (Ter) of the unique chromosome of most bacteria locates at mid-cell at the time of cell division. In several species, this localization participates in the necessary coordination between chromosome segregation and cell ...
