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, Volume 604, Issue 16, Page 6943-6958, 15 August 2026.
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 ...

Sequence motifs that distinguish ATP(CTP) : tRNA nucleotidyl transferases from eubacterial poly(A) polymerases [PDF]

, 2004
ATP(CTP):tRNA nucleotidyl transferases, tRNA maturing enzymes found in all organisms, and eubacterial poly(A) polymerases, enzymes involved in mRNA degradation, are so similar that until now their biochemical functions could not be distinguished by their

Elucidation of DNA Primase as a Drug Target in Leishmania donovani: Structure‐Guided Inhibitor Identification and Biochemical Validation

Chemical Biology &Drug Design, Volume 108, Issue 1, July 2026.
Structure‐guided and biochemical analyses indicate that DNA primase of Leishmania donovani represents a potential therapeutic target, as repurposed compounds, particularly Pritelivir, demonstrate marked inhibitory effects accompanied by reduced parasite proliferation, replication, and altered cellular morphology in in vitro and cell‐based studies ...

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.

“ADP Sulfurylase” from Thiobacillus denitrificansIs an Adenylylsulfate:Phosphate Adenylyltransferase and Belongs to a New Family of Nucleotidyltransferases*

Journal of Biological Chemistry, 2000
During AMP-dependent sulfite oxidation by some sulfur bacteria, the liberation of sulfate from adenosine-5′-phosphosulfate (APS) is catalyzed by APS:phosphate adenylyltransferase (APAT).

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

Divergent Evolution of Eukaryotic CC- and A-Adding Enzymes [PDF]

Synthesis of the CCA end of essential tRNAs is performed either by CCA-adding enzymes or as a collaboration between enzymes restricted to CC- and A-incorporation. While the occurrence of such tRNA nucleotidyltransferases with partial activities seemed to

The toxin–antitoxin complex Fic‐1–AntF functions as a deAMPylase that regulates the activity of DNA gyrase

mLife, Volume 5, Issue 3, Page 301-311, June 2026.
Abstract Toxin–antitoxin (TA) systems found in diverse bacteria play important roles in their adaptation to changing environments. The toxin of the Fic‐1–AntF TA pair from Pseudomonas bijieensis strain 2P24 inhibits bacterial DNA replication by attacking the subunit B of DNA gyrase (GyrB) via AMPylation, while the antitoxin AntF blocks its enzymatic ...

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.
