Bacterial autolysins trim cell surface peptidoglycan to prevent detection by the Drosophila innate immune system

eLife, 2014
Bacteria have to avoid recognition by the host immune system in order to establish a successful infection. Peptidoglycan, the principal constituent of virtually all bacterial surfaces, is a specific molecular signature recognized by dedicated host ...

Universal and Lineage‐Specific Patterns in the Distribution of ECOD Domain Homology Groups Across Superkingdoms

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Proteins are built from modular domains that serve as fundamental units of structure and evolution. While individual domains have been extensively cataloged, their collective distribution across the lineages of life has remained poorly resolved.

Determining bacteriophage endopeptidase activity using either fluorophore-quencher labeled peptides combined with liquid chromatography-mass spectrometry (LC-MS) or Förster resonance energy transfer (FRET) assays. [PDF]

PLoS ONE, 2017
The necessity of identifying novel methods to combat infections caused by antibiotic resistant bacteria is increasing each year. Recent advancements in the development of peptidoglycan hydrolases (e.g. lysins) from bacterial viruses (bacteriophages) have

Structural and Biochemical Characterization of the Diaminopimelate Epimerase DapF From Pseudomonas aeruginosa PA14

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The emergence of antibiotic resistance in bacteria is a major threat to global public health. To combat increasingly drug‐resistant bacteria like Pseudomonas aeruginosa, new targets for pharmaceuticals need to be explored. One such potential target for P.

Transcriptomic and proteomic signatures underlying nymphal adaptation and foam production in the forage pest Mahanarva spectabilis

Insect Molecular Biology, EarlyView.
RNA‐seq and Batelli gland proteomics of fifth‐instar Mahanarva spectabilis nymphs reveal transcripts and proteins associated with xylem feeding, foam production and environmental interaction. Functional annotation identified genes involved in osmoregulation, detoxification, chemosensation and stress responses, while proteomic analysis confirmed ...

Histiocytes: Multifaceted Regulators of Health and Disease

Veterinary Clinical Pathology, EarlyView.
ABSTRACT The mononuclear phagocyte system encompasses macrophages, dendritic cells (DCs), and monocytes. Tissue‐resident macrophages and dendritic cells arise during embryogenesis and are replenished either through self‐renewal or by monocytes during inflammation.

EV‐LYSG101: Extracellular Vesicles Loaded With Lysin LYSG101 for Potent Anti‐Staphylococcal Activity

Journal of Extracellular Biology, Volume 5, Issue 8, August 2026.
ABSTRACT Biofilm‐associated staphylococcal infections remain exceptionally difficult to treat due to the presence of resilient staphylococcal biofilms and the limited effectiveness of currently available antibiotics. To combat persistent infections, providers are often forced to use prolonged courses of combination antimicrobial therapies that have ...
