| Description | The unique coronavirus transcription/replication machinery comprised of multiple virus-encoded non structural proteins (NSP) plays a vital role during initial and intermediate phases of the viral life cycle. NSP15 forms a hexamer made of dimers of trimers which is suggested to be a functional unit, responsible for the endoribonuclease activity. The NSP15 monomer consists of three domains: N-terminal, middle and C-terminal [ , ]. The catalytic function of NSP15 resides in the C-terminal NendoU domain. The active site carries six key residues conserved among SARS-CoV-2, SARS-CoV and MERS-CoV, suggesting that its activity is important for sustained replication in the host [, ].This entry represents the non-catalytic middle domain of NSP15 from gammacoronaviruses. This domain is formed by ten beta strands organised into three beta hairpins. It creates concave surfaces that may serve as interaction hubs with other proteins and RNA [, ]. Coronavirus Nsp15 from Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV), human Coronavirus 229E (HCoV229E), and Murine Hepatitis Virus (MHV) form a functional hexamer. This middle domain harbours residues involved in hexamer formation and in trimer stability [, ]. Oligomerization of Porcine DeltaCoronavirus (PDCoV) Nsp15 differs from that of the other coronaviruses; it has been shown to exist as a dimer and a monomer in solution and that it inhibits type I interferon production independently of its endoribonuclease activity [, ]. |
