AbstractIn the gastric pathogen Helicobacter pylori, post-transcriptional regulation relies strongly on the activity of the essential ribonuclease RNase J.

We found that RNase J extracted from H. pylori is acetylated on multiple lysine residues. Alanine substitution of several of these residues impacts on H. pylori morphology, and thus on RNase J function in vivo.
