Transcriptome profiling of Nudix hydrolase gene deletions in the thermoacidophilic archaeon Sulfolobus acidocaldarius [PDF]
Frontiers in Microbiology, 2023 Nudix hydrolases comprise a large and ubiquitous protein superfamily that catalyzes the hydrolysis of a nucleoside diphosphate linked to another moiety X (Nudix).

Higher-Order Structure in Bacterial VapBC Toxin-Antitoxin Complexes
, 2017 Toxin-antitoxin systems are widespread in the bacterial kingdom, including in pathogenic species, where they allow rapid adaptation to changing environmental conditions through selective inhibition of key cellular processes, such as DNA replication or protein translation.

Journal of Molecular Biology, 2011 Toxin-antitoxin (TA) loci are common in archaea and prokaryotes and allow cells to rapidly adapt to changing environmental conditions through release of active regulators of metabolism. Many toxins are endonucleases that target cellular mRNA and tRNAs, while the antitoxins tightly wrap around the toxins to inhibit them under normal circumstances.

Environmental microbiology, 2014 The symbiotic nitrogen-fixing soil bacterium Sinorhizobium meliloti carries a large number of toxin-antitoxin (TA) modules both on the chromosome and megaplasmids. One of them, the vapBC-5 module that belongs to the type II systems was characterized here. It encodes an active toxin vapC-5, and was shown to be controlled negatively by the complex of its

The VapBC Toxin-Antitoxin systems : regulators of the nitrogen-fixing symbiosis Rhizobium-Legume
, 2020 Lors de la symbiose fixatrice d’azote entre la légumineuse modèle Medicago truncatula et la rhizobiacée Sinorhizobium meliloti, les bactéries, différenciées en bactéroïdes dans la nodosité, réduisent l’azote atmosphérique (N2) en ammoniac (NH3), directement assimilable par la plante.
