- Journal of bacteriology.J Bacteriol.2016 Oct 3. pii: JB.00624-16. [Epub ahead of print]
- Gene regulation by base-pairing between small non-coding RNAs (sRNAs) and their mRNA targets is an important mechanism that allows bacteria to maintain homeostasis and respond to dynamic environments. In Gram negative bacteria, sRNA pairing and regulation is mediated by several RNA-binding proteins,

- A phosphorolytic activity has been reported for beta-N-acetylglucosaminidases from glycoside hydrolase family 3 (GH3) giving an interesting explanation for an unusual histidine as catalytic acid/base residue and suggesting that members from this family may be phosphorylases [J. Biol. Chem. 2015, 290

- SAMHD1 plays diverse roles in innate immunity, autoimmune diseases and HIV restriction, but the mechanisms involved are still unclear. SAMHD1 has been reported to have both dNTPase and RNase activities. However, whether SAMHD1 possesses RNase activity remains highly controversial. Here, we found tha
