Emergence of 4',4"-aminoglycoside nucleotidyltransferase in enterococci [PDF]

Antimicrobial Agents and Chemotherapy, 1990
Enterococcus faecium BM4102 was resistant to macrolide-lincosamide-streptogramin B-type (MLS) antibiotics; tetracycline-minocycline; and high levels of kanamycin, neomycin, tobramycin, and dibekacin but not gentamicin. This aminoglycoside resistance phenotype is new in enterococci.

Ro5‐4864, a ligand of the mitochondrial translocator protein, protects against heart failure in mice via regulation of the p62‐Keap1‐Nrf2 axis

The Journal of Physiology, EarlyView.
Abstract figure legend Graphical abstract of the proposed Ro5‐4864 mechanism of action via p62‐Keap1‐Nrf2 axis in heart failure. TSPO, the 18‐kDa mitochondrial translocator protein of the outer mitochondrial membrane, can directly interact with p62 (also known as SQSTM1), which is crucial for the degradation of damaged mitochondria by autophagy ...

Molecular cloning of a novel glucuronokinase/putative pyrophosphorylase from zebrafish acting in an UDP-glucuronic acid salvage pathway.

PLoS ONE, 2014
In animals, the main precursor for glycosaminoglycan and furthermore proteoglycan biosynthesis, like hyaluronic acid, is UDP-glucuronic acid, which is synthesized via the nucleotide sugar oxidation pathway.

Epigenetic Aging in Brain Tissue of the Self‐Fertilizing Vertebrate, Kryptolebias marmoratus

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Using the self‐fertilizing vertebrate Kryptolebias marmoratus, we developed an epigenetic clock from brain tissue that predicts chronological age with high accuracy, demonstrating that DNA methylation changes consistently with age even in the near absence of genetic variation. The 40 age‐associated CpG sites identified map to genes with conserved roles

Thermodynamics of binding of divalent magnesium and manganese to uridine phosphates: implications for diabetes-related hypomagnesaemia and carbohydrate biocatalysis

Chemistry Central Journal, 2008
Background Although the necessity of divalent magnesium and manganese for full activity of sugar nucleotidyltransferases and glycosyltransferases is well known, the role of these metal cations in binding the substrates (uridine 5'-triphosphate, glucose-1-

Whole‐Genome Sequence Profiling of Listeria innocua From Different Sources: Implications for Public Health

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
The studied strains, LIN_NWU_CNKT and LIN5_NWU_CNKT, exhibit invasiveness, pathogenicity, and MDR profiles. The isolation of these strains from food products and water underscores their significant public health implications, particularly in the context of the “One Health” concept.

Biochemical Engineering Perspective on cGAS: From Enzyme Discovery to Potential Industrial Application

ChemBioChem, Volume 27, Issue 5, 13 March 2026.
This review examines the structural and enzymatic properties of cyclic GMP‐AMP synthase, including substrate promiscuity, homologs, and engineered variants. In addition, it evaluates potential expression systems for large‐scale enzyme production and analyzes reaction and purification strategies for the synthesis of cyclic dinucleotides to connect ...
