Helicobacter pylori RNase Y

Ribonucleases are involved in several biological processes, including the turnover of structural and messenger RNAs and the specific processing of the cellular transcriptome. Here, we characterized the RNase Y from Helicobacter pylori.We found that RNase Y is membrane-associated and its expression is controlled during bacterial growth and by Fur in response to iron. We observed that RNase Y deletion has a limited impact on H. pylori transcriptome as well as on bacterial growth.
