A Eubacterial Origin for the Human tRNA Nucleotidyltransferase? [PDF]

Biological Chemistry, 2001
tRNA CCA-termini are generated and maintained by tRNA nucleotidyltransferases. Together with poly(A) polymerases and other enzymes they belong to the nucleotidyltransferase superfamily. However, sequence alignments within this family do not allow to distinguish between CCA-adding enzymes and poly(A) polymerases. Furthermore, due to the lack of sequence

Microbial profile of the appendix niche in acute appendicitis: a novel sampling approach

FEBS Open Bio, Volume 15, Issue 12, Page 2001-2020, December 2025.
This study utilized a novel sampling method, ERAT (i.e. endoscopic retrograde appendicitis treatment)‐guided lumen aspiration, to obtain samples from the appendix, and shotgun metagenomic sequencing was performed for in situ characterization of the appendix microbiome in patients with acute appendicitis.

Polymorphic toxin systems: Comprehensive characterization of trafficking modes, processing, mechanisms of action, immunity and ecology using comparative genomics

Biology Direct, 2012
Background Proteinaceous toxins are observed across all levels of inter-organismal and intra-genomic conflicts. These include recently discovered prokaryotic polymorphic toxin systems implicated in intra-specific conflicts.

Aminoglycoside-4'-nucleotidyltransferase from Bacillus brevis.

Agricultural and Biological Chemistry, 1980
The existence of aminoglycoside-4′-nucleotidyltransferase [AAD(4′)] was demonstrated in the cell-free extract of B. brevis. This enzyme was purified about 100-fold over the cell-free extract by column chromatography using DEAE-cellulose and affinity chromatography using butirosin A-Sepharose 4B.AAD(4′) of B. brevis catalyzed the transfer of nucleotides

The Role and Therapeutic Potential of the cGAS‐STING Signaling Pathway in Alzheimer's Disease

Brain and Behavior, Volume 15, Issue 12, December 2025.
This work reveals the relationship between the cGAS‐STING signaling pathway and the pathological mechanisms of Alzheimer's disease.The role of the cGAS‐STING signaling pathway in AD pathology. AD leads to the production of neutrophil extracellular traps (NETs), endoplasmic reticulum (ER) stress, and the release of mitochondrial DNA (mtDNA) and nuclear ...

Breaking barriers: The cGAS‐STING pathway as a novel frontier in cancer immunotherapy

Cancer Communications, Volume 45, Issue 11, Page 1513-1546, November 2025.
Abstract Since its discovery, the cyclic GMP‐AMP synthase (cGAS)‐stimulator of the interferon gene (STING) signaling pathway has been considered a pivotal component of innate immunity and a promising target for cancer immunotherapy. Beyond its canonical role in pathogen defense, accumulating evidence has demonstrated that the cGAS‐STING pathway ...
