Exploring Oxygen Electrocatalysis in Phosphonium Ionic Liquids Towards Sodium–Oxygen Batteries

ChemElectroChem, Volume 13, Issue 7, 1 April 2026.
Sodium–oxygen (Na–O2) batteries are attractive candidates for high‐energy storage systems; however, their long‐term operation is hindered by the instability of highly reactive intermediates such as the superoxide anion (O2•−). Ionic liquids (ILs) have emerged as promising electrolytes not only because of their intrinsic safety but also due to their ...

Mutations in the FtsW/FtsI/FtsN complex suppress SidA and DidA overproduction phenotypes. [PDF]

, 2014
(A) Schematic showing the membrane topology of FtsW, FtsI, FtsN, SidA, and DidA. Missense mutations and the GFP-FtsN fusion that suppress the activities of SidA or DidA, or both, are listed in red.

Prevalence of Resistance to β-Lactam Antibiotics and bla Genes Among Commensal Haemophilus parainfluenzae Isolates from Respiratory Microbiota in Poland

Microorganisms, 2019
(1) Background: Beta-lactams are the most frequently used antimicrobials, and are the first-line drugs in many infectious diseases, e.g., pneumonia, otitis media. Due to this fact, various bacteria have developed resistance to this group of drugs.

A promoter for the first nine genes of the Escherichia coli mra cluster of cell division and cell envelope biosynthesis genes, including ftsI and ftsW [PDF]

Journal of Bacteriology, 1997
We constructed a null allele of the ftsI gene encoding penicillin-binding protein 3 of Escherichia coli. It caused blockage of septation and loss of viability when expression of an extrachromosomal copy of ftsI was repressed, providing a final proof that ftsI is an essential cell division gene.

SanA Plays a Role in Peptidoglycan Integrity in Escherichia coli

Molecular Microbiology, Volume 125, Issue 4, Page 343-357, April 2026.
SanA is a novel regulator of peptidoglycan synthesis, potentially through functional interplay with PBP1B‐dependent pathways. ABSTRACT Peptidoglycan synthesis and degradation are both essential for bacterial growth, and damaged peptidoglycan must be continuously repaired. In Escherichia coli, peptidoglycan required for cell elongation is synthesized by

Morphology of Hydrophilic and Hydrophobic Domains are the Key to Improve Fouling Release of Polyurethane Coatings

Macromolecular Materials and Engineering, Volume 311, Issue 1, January 2026.
Marine biofouling is strongly decreased by polarity gradients of two‐phase coatings which in addition show a distinct topography and wrinkled surface microstructures with stiff gradients. These material properties collectively reduce the adhesion strength, debase settlement dynamics and ultimately improve the overall fouling release performance of ...

Cefuroxime resistance in non-β-lactamase Haemophilus influenzae is linked to mutations in ftsI [PDF]

, 2003
The penicillin binding protein (PBP) genes dacA, dacB and ftsI from 14 cefuroxime-resistant (CXM(R)) isolates and three clinical isolates with low CXM MIC for non-beta-lactamase-producing Haemophilus influenzae type b were molecularly characterized.

Genotypic versus Phenotypic Characterization, with Respect to β-Lactam Susceptibility, of Haemophilus influenzae Isolates Exhibiting Decreased Susceptibility to β-Lactam Resistance Markers [PDF]

, 2009
Among 165 Spanish Haemophilus influenzae isolates with mutations in the ftsI gene (ftsI+) (2005 to 2007), 73% were β-lactamase negative and 26.7% were positive. The proportion of β-lactamase-negative isolates to β-lactamase-positive isolates was 2:1 to 4:
