Mechanism of Mg2+-Accompanied Product Release in Sugar Nucleotidyltransferases [PDF]
The nucleotidyl transfer reaction, catalyzed by sugar nucleotidyltransferases (SNTs), is assisted by two active site Mg2+ ions. While studying this reaction using X-ray crystallography, we captured snapshots of the pyrophosphate (product) as it exits along a pocket.

Molecular mechanisms of template-independent RNA polymerization by tRNA nucleotidyltransferases [PDF]
The universal 3'-terminal CCA sequence of tRNA is built and/or synthesized by the CCA-adding enzyme, CTP:(ATP) tRNA nucleotidyltransferase. This RNA polymerase has no nucleic acid template, but faithfully synthesizes the defined CCA sequence on the 3 ...

ant(6)-I Genes Encoding Aminoglycoside O-Nucleotidyltransferases Are Widely Spread Among Streptomycin Resistant Strains of Campylobacter jejuni and Campylobacter coli [PDF]
Thermotolerant Campylobacter species C. jejuni and C. coli are actually recognized as the major bacterial agent responsible for food-transmitted gastroenteritis. The most effective antimicrobials against Campylobacter are macrolides and some, but not all

Bacterial glycomes are rich in prokaryote-specific or “rare” sugars that are absent in mammals. Like common sugars found across organisms, rare sugars are typically activated as nucleoside diphosphate sugars (NDP-sugars) by nucleotidyltransferases.

Identification and Characterization of Mammalian Mitochondrial tRNA nucleotidyltransferases [PDF]
The CCA-adding enzyme (ATP:tRNA adenylyltransferase or CTP:tRNA cytidylyltransferase (EC 2.7.7.25)) generates the conserved CCA sequence responsible for the attachment of amino acid at the 3′ terminus of tRNA molecules.

Structures and mechanism of E2‐CBASS anti‐phage system
Bacteria deploy diverse innate immune systems to combat bacteriophage infections. The cyclic‐oligonucleotide‐based anti‐phage signaling system (CBASS) is a type of innate prokaryotic immune system.
