Recognition of the tRNA-like structure in tobacco mosaic viral RNA by ATP/CTP:tRNA nucleotidyltransferases from Escherichia coli and Saccharomyces cerevisiae.

Journal of Biological Chemistry, 1990
The 3'-terminal tRNA-like structure of the tobacco mosaic virus RNA interacts with ATP/CTP:tRNA nucleotidyltransferases from Escherichia coli or yeast in much the same manner as do tRNAs.

The structural basis of the catalytic mechanism and regulation of glucose-1-phosphate thymidylytransferase (Rm/A)

, 2000
The synthesis of deoxy-thymidine di-phosphate (dTDP)-L-rhamnose, an important component of the cell wall of many microorganisms, is a target for therapeutic intervention. The first enzyme in the dTDP-L-rhamnose biosynthetic pathway is glucose-1-phosphate

Small Extracellular Vesicles in Gestational Diabetes Mellitus: Current Landscape and Emerging Diagnostic Horizons

Journal of Extracellular Biology, Volume 5, Issue 3, March 2026.
ABSTRACT Gestational diabetes mellitus (GDM) is a common metabolic disorder of pregnancy associated with significant maternal and neonatal morbidity and mortality. Current diagnostic strategies, particularly the oral glucose tolerance test (OGTT), are limited by late detection, variability in diagnostic criteria, and patient burden, highlighting the ...

An inhibitory C-terminal region dictates the specificity of A-adding enzymes

, 2011
For efficient aminoacylation, tRNAs carry the conserved 3′-terminal sequence C-C-A, which is synthesized by highly specific tRNA nucleotidyltransferases (CCA-adding enzymes).

Divergent Evolution of Eukaryotic CC- and A-Adding Enzymes

, 2020
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 potato cyst nematode Globodera pallida overcomes major potato resistance through selection on standing variation at a single locus

New Phytologist, Volume 249, Issue 6, Page 3039-3059, March 2026.
Summary Globodera pallida poses a major threat to potato production, with management strategies primarily relying on genetic resistance. However, increasing virulence in field populations across Western Europe raises major concerns for G. pallida control.

Virulence Regulation and Lifestyle Transitions: The Role of c‐di‐GMP and Two‐Component Systems in Erwinia amylovora and Their Evolutionary Context Within Enterobacterales

Molecular Plant Pathology, Volume 27, Issue 2, February 2026.
Erwinia amylovora infects apple blossoms by activating the T3SS, then spreads systemically via amylovoran‐mediated biofilms. Transitions between motile and sessile states are regulated by key two‐component systems and c‐di‐GMP. This review summarises infection biology, virulence factors, regulatory networks and evolutionary insights underlying fire ...
