Peptidoglycan structure and architecture

open access: yes
The peptidoglycan (murein) sacculus is a unique and essential structural element in the cell wall of most bacteria. Made of glycan strands cross-linked by short peptides, the sacculus forms a closed, bag-shaped structure surrounding the cytoplasmic ...

D‐amino acid oxidase as a chemogenetic tool for spatiotemporally controlled hydrogen peroxide production: The oxygen connection

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose D‐amino acid oxidase (DAO) has been developed as a chemogenetic tool, to precisely manipulate redox levels in tissues and cells by generating H2O2 in the presence of D‐amino acids. The enzyme's significant oxygen consumption during H2O2 production may influence cellular oxygen levels.

Microbiome–Driven Carcinogenesis and Circulating Microbial Signals in Genitourinary Cancers

open access: yesCancer Science, EarlyView.
Experimental BBN models link gut microbial metabolism and diet‐microbiome interactions to urothelial carcinogenesis, while circulating extracellular vesicle‐associated bacterial DNA signals may reflect tumor immune contexture and immune checkpoint inhibitor outcomes in urothelial and renal cell carcinoma.

Peptidoglycan : structure, biological activity and chemical synthesis

open access: yes, 2015
The most important component of bacterial cell walls especially Gram-positive bacteria is peptidoglycan, called also murein, PGN. The first time this synonym was used in 1964 by Weidel and Pelzer [1].

Role of human RNase 7 in neuronal and glial cell models: moving towards an unexpected new functional link

open access: yesThe FEBS Journal, EarlyView.
Human RNase 7 is known to exert antimicrobial activity in epithelial tissues. Here, using SH‐SY5Y and U‐87 MG, neuroblastoma and glioblastoma cell lines, respectively, we found that RNase 7 enhances immune responses to LPS stimulation by reducing the expression of pro‐inflammatory cytokines, nitric oxide, and ROS.

ADAM17 and its proteolytic targets in disease pathogenesis

open access: yesThe FEBS Journal, EarlyView.
ADAM17 as a multifunctional sheddase with contrasting roles across inflammatory, metabolic, cardiovascular, and neoplastic diseases. Through regulated activation by iRhom, iTAP/FRMD8, and tetraspanins, ADAM17 cleaves diverse membrane ligands and receptors, thereby promoting inflammation, fibrosis, obesity, insulin resistance, and tumor progression ...

Cryo‐EM structures of multiple‐peptide resistance factor (MprF) from Pseudomonas aeruginosa

open access: yesThe FEBS Journal, EarlyView.
Cryo‐EM analysis of MprF from Pseudomonas aeruginosa reveals a dimeric enzyme, distinct from Rhizobium homologues. The soluble GNAT domain contains a dynamic amphipathic helix (TTH) that adopts different positions in detergent micelle and nanodisc, relative to the membrane.

A distinct gene expression mechanism for d‐amino acid utilization in hyperthermophilic archaeon Pyrococcus horikoshii

open access: yesThe FEBS Journal, EarlyView.
The genes PH0137, PH0138, and PH0140 form a cluster in the genome of Pyrococcus horikoshii. The PH0140 gene encodes a transcription factor identified as a d‐amino acid‐responsive regulatory protein (DARP). In feast mode, l‐Ile‐bound DARP binds to the promoter and represses transcription of PH0137 and PH0138. In famine mode, DARP binds to d‐allo‐Ile and

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

open access: yesInsect 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 ...
