Non-structural proteins of SARS-CoV-2 and their functions52.

Non-structural proteins of SARS-CoV-2 Functions
Nsp1 Ensures RNA processing and replication (PDB: 6ZOK, 2GDT)
Nsp2 Modulates the host cell survival signalling pathway (PDB: 7EXM)
Nsp3 Separates proteins that are translated (PLpro) (PDB: 6W02, 5Y3E)
Nsp4 Contains a transmembrane domain (TM2) and modifies membranes
Nsp5 The main protease (Mpro), participates in the process of cleavage of polyprotein during replication (PDB: 1WOF, 1Z1J, 2C3C)
Nsp6 Is the transmembrane domain
Nsp7 Has an effect on RNA-dependent RNA polymerase (PDB: 1YSY)
Nsp8 The presence of nsp7, nsp8, and nsp11 affects RNA-dependent RNA polymerase and coronavirus replication/transcription
Nsp9 Functioning as an ssRNA-binding protein
Nsp10 Is crucial for cap-methylation of viral mRNAs (PDB: 2G9T)
Nsp11 Together with nsp7, nsp8 targets RNA-dependent RNA polymerase and coronavirus replication/transcription
Nsp12 Contains RNA-dependent RNA polymerase (RdRp), which is a critical component of coronavirus replication/transcription
Nsp13 The zinc-binding domain of nsp13 is involved in replication and transcription processes (PDB: 6XEZ, 7EIZ)
Nsp14 Proofreading exoribonuclease domain
Nsp15 Has Mn2+-dependent endoribonuclease activity (PDB: 6VWW)
Nsp16 2′-O-ribosemethyltransferase (PDB: 6WKS)
