A Short Introduction to Bacteriophages

Trends in Peptide and Protein Sciences, 2016
First discovered in the 19th century, bacteriophages (phages) are bacterial viruses and the most widespread entities on earth. Phages have multiple important roles in maintaining the bacterial population, carbon cycling, bacterial pathogenicity, and ...

The Role of torS and torT Transcription in Driving a Bet‐Hedging Strategy for Trimethylamine N‐Oxide Reductase Expression in Escherichia coli

Molecular Microbiology, EarlyView.
Low basal activity of divergent promoters driving transcription of the trimethylamine N‐oxide (TMAO) sensor TorT and kinase TorS is integral to an O2‐regulated bet‐hedging strategy for continued E. coli growth upon the onset of anaerobiosis. This, along with repression by IscR, promotes noise in the TorS to TorT ratio, which is critical for adaptation ...

Prevalence, Host Range, and Comparative Genomic Analysis of Temperate Ochrobactrum Phages

Frontiers in Microbiology, 2017
Ochrobactrum and Brucella are closely related bacteria that populate different habitats and differ in their pathogenic properties. Only little is known about mobile genetic elements in these genera which might be important for survival and virulence ...

Oral Phageome as Potential Modulators of Periodontal Dysbiosis. A Systematic Review

Oral Diseases, EarlyView.
ABSTRACT Introduction The oral phageome, comprising bacteriophages inhabiting the oral cavity, has been proposed as a potential modulator of periodontal health and disease. This systematic review synthesizes current evidence on interactions between bacteriophages, key periodontal bacteria, and the host in periodontitis.

Comparative analysis of immune responses in ovipositing and non‐ovipositing females of European earwig Analyse comparative de la réponse immunitaire avant et après la ponte chez le forficule européen

Physiological Entomology, EarlyView.
Oviposition and care decrease the total haemocyte concentration. Oviposition and care affect haemocyte type proportions. Serratia marcescens challenge does not affect the immune cell parameters. Abstract Reproduction and immunity are essential biological processes that compete for resources and energy.

Saturating mutagenesis on the Ser118 residue responsible for the spectral tuning mechanism of the orange/green‐reversible cyanobacteriochrome AM1_1499g1

Plant Biology, EarlyView.
This graphical abstract illustrates our systematic site‐saturation mutagenesis at the Ser118 position of the AM1_1499g1 GAF domain. By replacing this single residue, we generated a diverse array of variants with distinct spectral properties, demonstrating the remarkable molecular plasticity of cyanobacteriochromes and their customizability for ...

Role of RIPK1/RIPK3/MLKL signalling pathway in sepsis‐associated acute kidney injury

Experimental Physiology, EarlyView.
Abstract Sepsis‐associated acute kidney injury (SA‐AKI) is a common clinical syndrome in critically ill patients, and its high mortality rate is closely related to complex pathological mechanisms. Existing studies have shown that the pathophysiological process of SA‐AKI involves complex multi‐mechanism interactions, including an uncontrolled systemic ...

Quaternary structures of Streptococcus pneumoniae nucleoside diphosphate kinase: From hexamers to supramolecular assemblies

Protein Science, Volume 35, Issue 9, September 2026.
Abstract The nucleoside diphosphate kinase (NDK) is a key enzyme that controls the balance of nucleotide pools in all living organisms. Beyond this fundamental role, NDKs exert pleiotropic effects in many cellular processes, including cell development, signal transduction, differentiation, tumor metastasis, and gene expression. The quaternary structure

Prophages and their interactions with lytic phages in the human gut microbiota and their impact on microbial diversity, gut health, and disease

Applied and Environmental Microbiology
Bacteriophages (phages), the dominant prokaryotic viruses that specifically target bacteria in the human gut microbiome, play a crucial role in maintaining intestinal balance, regulating bacterial populations, and preserving microbial diversity within ...

Sequence‐encoded determinants drive distinct early aggregation pathways and different structural outcomes in PNT1 fibrils across Henipavirus members

Protein Science, Volume 35, Issue 9, September 2026.
Abstract Protein aggregation is increasingly recognized as a biologically relevant process in viral proteins, yet the molecular determinants governing such phenomena remain poorly understood. Intrinsically disordered proteins (IDPs) are ubiquitous in viral proteomes, where conformational plasticity not only enables functional diversity but also permits
