Structural basis for CRISPR RNA-guided DNA recognition by Cascade [PDF]

open access: yes, 2011
The CRISPR (clustered regularly interspaced short palindromic repeats) immune system in prokaryotes uses small guide RNAs to neutralize invading viruses and plasmids.

Efficient Self‐Cleaning and Anti‐Bacterial Behavior Realized by Hierarchical Structure in Hybrid Waterborne Polyurethane Coatings Containing Photocatalyst

open access: yesAdvanced Materials Interfaces, EarlyView.
Hybrid WPU coatings with a hierarchical structure are constructed by first directional freezing polymerization of degradable hydrogels with a vertical channel structure and then filling these channels with aqueous WPU solution containing carbon nitride (g‐C3N4) nanosheets.

The DigH glycosyl hydrolase is conditionally required for daughter cell separation in Escherichia coli

open access: yesJournal of Bacteriology
The peptidoglycan (PG) cell wall is a mesh-like layer that shapes bacteria and protects against osmotically induced lysis. PG is composed of glycan strands and peptide chains that link together to form a continuous layer that surrounds the cell.

Escherichia coli peptidoglycan structure and mechanics as predicted by atomic-scale simulations.

open access: yesPLoS Computational Biology, 2014
Bacteria face the challenging requirement to maintain their shape and avoid rupture due to the high internal turgor pressure, but simultaneously permit the import and export of nutrients, chemical signals, and virulence factors.

The Effects of Eugenol, Trans-Cinnamaldehyde, Citronellol, and Terpineol on Escherichia coli Biofilm Control as Assessed by Culture-Dependent and -Independent Methods

open access: yesMolecules, 2020
Bacterial biofilms contribute to problems with preserving food hygiene, jeopardizing any conventional intervention method used by the food industry. Hence, the approach of using essential oil (EO) compounds effective in biofilm control has considerable ...

[Evaluation of the effect of glucose on Staphylococcus aureus and Escherichia coli biofilm formation on the surface of polypropylene mesh].

open access: yesMedycyna doswiadczalna i mikrobiologia, 2013
One of the most serious complications associated with the use of implants in hernia surgery is deep surgical site infection involving an implanted biomaterial. Among the major etiological factors of this complication are Staphylococcus aureus and Escherichia coli strains, which have the ability to form a biofilm on the surface of the mesh implant. This

Enhanced Infection Resistance and Regenerative Healing of Titanium Implants via Peptide‐Loaded Biodegradable Coatings

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a new biodegradable coating for titanium implants using a natural antimicrobial peptide, caerin 1.9. Applied via solvent casting, the coating offers sustained antibacterial protection and promotes healing. Tested on 3D‐printed porous titanium scaffolds, it effectively prevented infection—including against resistant bacteria—while ...

Numerical simulation of growth of Escherichia coli in unsaturated porous media [PDF]

open access: yes, 2014
A model for the aerobic and anaerobic growth of Escherichia coli (HB101 K12 pGLO) depending on the concentration of oxygen and DOC as substrate has been developed based on laboratory batch experiments.

Endocytic Control of Cell‐Autonomous and Non‐Cell‐Autonomous Functions of p53

open access: yesAdvanced Science, EarlyView.
NUMB Ex3‐containing isoforms localize to the plasma membrane, where they recruit p53 through SNX9 and direct it to multivesicular bodies and exosomes. Exported p53 is taken up by neighboring cells and activates nuclear programs, revealing an intercellular, exosome‐based pathway that might help establish a tumor‐suppressive microenvironment.

Solution structure of a bacterial microcompartment targeting peptide and its application in the construction of an ethanol bioreactor [PDF]

open access: yes, 2014
Targeting of proteins to bacterial microcompartments (BMCs) is mediated by an 18-amino-acid peptide sequence. Herein, we report the solution structure of the N-terminal targeting peptide (P18) of PduP, the aldehyde dehydrogenase associated with the 1,2 ...
