The emergence of SARS-CoV-1 in 2003 followed by MERS-CoV and now SARS-CoV-2 has proven the latent threat these viruses pose to humanity. While the SARS-CoV-2 pandemic has shifted to a stage of endemicity, the threat of new coronaviruses emerging from ...

Flipped Over U: Structural Basis for dsRNA Cleavage by the SARS-CoV-2 Endoribonuclease
Coronaviruses generate double-stranded (ds) RNA intermediates during viral replication that can activate host immune sensors. To evade activation of the host pattern recognition receptor MDA5, coronaviruses employ Nsp15, which is uridine-specific ...

Significance Middle East respiratory syndrome coronavirus (MERS-CoV) causes highly lethal respiratory disease. MERS-CoV encodes innate immune antagonists, including accessory proteins NS4a and NS4b, unique to the merbeco lineage of betacoronaviruses, and

Kawasaki disease (KD) is the leading cause of noncongenital heart disease in children. Studies in mice and humans propound the NLRP3/IL-1β pathway as the principal driver of KD pathophysiology.

Sequence-specific endoribonucleases
Ribonucleases are nucleolytic enzymes that commonly occur in living organisms and act by cleaving RNA molecules. These enzymes are involved in basic cellular processes, including the RNA maturation that accompanies the formation of functional RNAs, as well as RNA degradation that enables removal of defective or dangerous molecules or ones that have ...

Allosteric regulation and crystallographic fragment screening of SARS-CoV-2 NSP15 endoribonuclease
SARS-CoV-2 is the causative agent of COVID-19. The highly conserved viral NSP15 endoribonuclease, NendoU, is a key enzyme involved in viral immune evasion, and a promising target for the development of new classes of antivirals. Yet, the broad variety of

Colicin E3: A Unique Endoribonuclease [PDF]
The question of whether or not a cellular ribonuclease is involved in the cleavage of 16S ribosomal RNA by colicin E3 was investigated. For this purpose ribosomes from strains devoid of some ribonucleases or ribosomes in which ribonucleases had been inactivated by heat or removed by extensive washings were used for the colicin reaction.

Endoribonuclease non-structural protein 15 (nsp15) (EndoU) is conserved among coronaviruses (CoVs) and is crucial for viral replication, evasion of the innate immune system, and virulence.
