Genome‐Wide In Silico Analysis of the Type VI Secretion System (T6SS) Within the Morganella Genus
MicrobiologyOpen, Volume 15, Issue 3, June 2026.▪ Species‐specific T6SS patterns among Morganella genus (M. morganii and M. sibonii). ▪ Only one‐third of M. morganii isolates haboured a T6SS. ▪ All M. sibonii possess four T6SS clusters. ▪ M. sibonii exhibited a wide diversity of effectors compared to M. morganii.

RNA Recognition and Cleavage by the SARS Coronavirus Endoribonuclease
Journal of Molecular Biology, 2006 The emerging disease SARS is caused by a novel coronavirus that encodes several unusual RNA-processing enzymes, including non-structural protein 15 (Nsp15), a hexameric endoribonuclease that preferentially cleaves at uridine residues. How Nsp15 recognizes and cleaves RNA is not well understood and is the subject of this study.

Immune Evasion of Helicobacter pylori and Extra‐Gastric Cancer Risk
Journal of Gastroenterology and Hepatology, Volume 41, Issue 6, Page 1722-1742, June 2026.ABSTRACT Helicobacter pylori (H. pylori) is a group 1 gastric carcinogen that plays a significant role in extra‐gastric digestive system cancers. H. pylori disrupts host cell homeostasis through expression of virulence factors leading to immune evasion as well as persistent gastric mucosal colonization. H. pylori infection has been shown to play a role

Structural basis for human mitochondrial tRNA maturation
Nature CommunicationsThe human mitochondrial genome is transcribed into two RNAs, containing mRNAs, rRNAs and tRNAs, all dedicated to produce essential proteins of the respiratory chain. The precise excision of tRNAs by the mitochondrial endoribonucleases (mt-RNase), P and Z,

Restoring Iron Homeostasis via Smoothened Inhibition: A Novel Strategy Against Hearing Loss
Advanced Science, Volume 13, Issue 29, 22 May 2026.. ABSTRACT Sensorineural hearing loss (SNHL) induced by noise or aminoglycoside antibiotics is a significant public health concern without any FDA‐approved pharmaceutical therapies. Dysregulation of iron homeostasis and its subsequently induced ferroptosis has increasingly been identified as a key mechanism underlying cochlear hair cell (HC) damage ...

CellsRemoval of RNA/DNA hybrids for the maturation of Okazaki fragments on the lagging strand, or due to misincorporation of ribonucleotides by DNA polymerases, is essential for all types of cells. In prokaryotic cells such as Escherichia coli, DNA polymerase

Towards new antituberculotic targets: biochemical characterisation of mycobacterial RNase E/G
European Respiratory Review, 2008 The World Health Organization estimates that each year 3 million people die from tuberculosis (TB) and 8 million people become infected. No new anti-TB drugs have been introduced in the past 30 years, even though their development becomes increasingly ...

Metal ions govern coronavirus endoribonuclease activity
Nucleic Acids ResearchAbstract Coronavirus nonstructural protein 15 (nsp15) is an endoribonuclease that restricts viral double-stranded RNA (dsRNA) accumulation in the cytosol to evade host immunity. Given the co-localization of nsp15 and replicating viral RNA, the mechanism controlling nsp15 activity is essential, yet poorly understood.
