A mutant defective in partitioning of composite plasmid Rms201 [PDF]

Journal of Bacteriology, 1981
Escherichia coli harboring mutant plasmids defective in maintenance stability (from the conjugative plasmid Rms201) showed a wide distribution of ampicillin resistance levels, as well as increased frequency of plasmid loss from the cell. The amounts of covalently closed circular deoxyribonucleic acid of mutant plasmid Rms268 and parental plasmid Rms201

Mistletoe‐ and Mussel‐Inspired Fabrication of Hierarchically Structured Protein‐Cellulose Scaffolds From Biomolecular Condensates

Advanced Materials, EarlyView.
Merging materials processing tricks inspired by mussel and mistletoe fiber fabrication, solutions of cationic mussel byssus proteins were mixed with modified anionic nanocrystalline cellulose, producing distinctive core‐shell condensates. Simple processing of condensate suspensions using freeze‐drying produced hierarchically structured porous protein ...

The new pLAI (lux regulon based auto-inducible) expression system for recombinant protein production in Escherichia coli

Microbial Cell Factories, 2012
Background After many years of intensive research, it is generally assumed that no universal expression system can exist for high-level production of a given recombinant protein.

Nuclear inclusion of nontargeted and chromatin-targeted polystyrene beads and plasmid DNA containing nanoparticles [PDF]

, 2011
The nuclear membrane is one of the major cellular barriers in the delivery of plasmid DNA (pDNA). Cell division has a positive influence on the expression efficiency since, at the end of mitosis, pDNA or pDNA containing complexes near the chromatin are ...

Cholesterol‐DNA Origami Nanostructures for Synthetic Lipid Rafts Induce Early T Cell Activation Signals

Advanced Materials Interfaces, EarlyView.
Here, we present a nanotechnology approach to construct synthetic lipid rafts on the live T cell membrane, leveraging a versatile DNA origami‐enabled platform named as the “cholesterol nano‐patch” (CNP). Our investigation highlights the effectiveness of DNA nanotechnology in exploring the impact of nanoscale arrangement of cholesterols on the ...

Phosphatidylserine polarization is required for proper Cdc42 localization and for development of cell polarity. [PDF]

, 2010
We used genetically-encoded fluorescent probes to visualize the distribution of phosphatidylserine (PS) in live S. cerevisiae. The majority of the PS was found to reside in the cytosolic leaflet of the plasma membrane.

Using cellular fitness to map the structure and function of a major facilitator superfamily effluxer. [PDF]

, 2017
The major facilitator superfamily (MFS) effluxers are prominent mediators of antimicrobial resistance. The biochemical characterization of MFS proteins is hindered by their complex membrane environment that makes in vitro biochemical analysis challenging.

Molecular Dissection of a Protein SopB Essential for Escherichia coli F Plasmid Partition*

Journal of Biological Chemistry, 1996
Biochemical and genetic experiments were carried out to deduce the structural and functional domains of SopB protein involved in the equipartition of F plasmid. The protein is dimeric. Proteolytic and chemical footprinting studies support earlier genetic

EIF1AX Nucleolar Condensates Enhance Susceptibilities for the Management of Endometrial Cancer

Advanced Science, EarlyView.
This schematic illustrates the mechanism of a senolytic strategy in endometrial cancer. EIF1AX facilitates the incorporation of DDX21 into nucleolar condensates, an event that suppresses rDNA transcription and induces cellular senescence. The compound 2,5‐MeC exploits this pathway by promoting EIF1AX nucleolar translocation and condensate formation ...

Protein stabilization explains the gag requirement for transformation of lymphoid cells by Abelson murine leukemia virus [PDF]

, 1985
The single protein encoded by Abelson murine leukemia virus is a fusion of sequence from the retroviral gag genes with the v-abl sequence. Deletion of most of the gag region from the transforming protein results in a virus capable of transforming ...
