Acetylation regulates the oligomerization state and activity of RNase J, the Helicobacter pylori major ribonuclease

open access: yesNature Communications, 2023
In the gastric pathogen Helicobacter pylori, post-transcriptional regulation relies strongly on the activity of the essential ribonuclease RNase J. Here, we elucidated the crystal and cryo-EM structures of RNase J and determined that it assembles into ...
