Enzyme Function FUNCTION: [Isoform Replicase polyprotein 1ab]: Multifunctional protein involved in the transcription and replication of viral RNAs. Contains the proteinases responsible for the cleavages of the polyprotein. {ECO:0000305}.; FUNCTION: [Host translation inhibitor nsp1]: Inhibits host translation by interacting with the 40S ribosomal subunit. The nsp1-40S ribosome complex further induces an endonucleolytic cleavage near the 5'UTR of host mRNAs, targeting them for degradation. Viral mRNAs are not susceptible to nsp1-mediated endonucleolytic RNA cleavage thanks to the presence of a 5'-end leader sequence and are therefore protected from degradation. By suppressing host gene expression, nsp1 facilitates efficient viral gene expression in infected cells and evasion from host immune response (PubMed:23035226). May disrupt nuclear pore function by binding and displacing host NUP93 (PubMed:30943371). {ECO:0000269|PubMed:23035226, ECO:0000269|PubMed:30943371}.; FUNCTION: [Non-structural protein 2]: May play a role in the modulation of host cell survival signaling pathway by interacting with host PHB and PHB2 (PubMed:19640993). Indeed, these two proteins play a role in maintaining the functional integrity of the mitochondria and protecting cells from various stresses (PubMed:19640993). {ECO:0000269|PubMed:19640993}.; FUNCTION: [Papain-like protease nsp3]: Responsible for the cleavages located at the N-terminus of the replicase polyprotein (PubMed:16306590). In addition, PL-PRO possesses a deubiquitinating/deISGylating activity and processes both 'Lys-48'- and 'Lys-63'-linked polyubiquitin chains from cellular substrates (PubMed:16306590, PubMed:17692280). Plays a role in host membrane rearrangement that leads to creation of cytoplasmic double-membrane vesicles (DMV) necessary for viral replication (PubMed:23943763). Nsp3, nsp4 and nsp6 together are sufficient to form DMV (PubMed:24410069). Antagonizes innate immune induction of type I interferon by blocking the phosphorylation, dimerization and subsequent nuclear translocation of host IRF3 (PubMed:19369340, PubMed:24622840). Prevents also host NF-kappa-B signaling (PubMed:19369340, PubMed:24622840). {ECO:0000269|PubMed:16306590, ECO:0000269|PubMed:17692280, ECO:0000269|PubMed:19369340, ECO:0000269|PubMed:23943763, ECO:0000269|PubMed:24622840, ECO:0000303|PubMed:24410069}.; FUNCTION: [Non-structural protein 4]: Plays a role in host membrane rearrangement that leads to creation of cytoplasmic double-membrane vesicles (DMV) necessary for viral replication (PubMed:23943763). Alone appears incapable to induce membrane curvature, but together with nsp3 is able to induce paired membranes. Nsp3, nsp4 and nsp6 together are sufficient to form DMV. {ECO:0000269|PubMed:23943763, ECO:0000303|PubMed:24410069}.; FUNCTION: [3C-like proteinase nsp5]: Cleaves the C-terminus of replicase polyprotein at 11 sites. Recognizes substrates containing the core sequence [ILMVF]-Q-|-[SGACN]. Also able to bind an ADP-ribose-1''-phosphate (ADRP). May cleave host ATP6V1G1 thereby modifying host vacuoles intracellular pH. {ECO:0000255|PROSITE-ProRule:PRU00772, ECO:0000269|PubMed:16226257}.; FUNCTION: [Non-structural protein 6]: Plays a role in host membrane rearrangement that leads to creation of cytoplasmic double-membrane vesicles (DMV) necessary for viral replication (PubMed:24991833, PubMed:24410069). Nsp3, nsp4 and nsp6 together are sufficient to form DMV (PubMed:24991833, PubMed:24410069). Plays a role in the initial induction of autophagosomes from host reticulum endoplasmic. Later, limits the expansion of these phagosomes that are no longer able to deliver viral components to lysosomes (PubMed:24991833). {ECO:0000269|PubMed:24991833, ECO:0000303|PubMed:24410069}.; FUNCTION: [Non-structural protein 7]: Forms a hexadecamer with nsp8 (8 subunits of each) that may participate in viral replication by acting as a primase. Alternatively, may synthesize substantially longer products than oligonucleotide primers. {ECO:0000269|PubMed:22039154}.; FUNCTION: [Non-structural protein 8]: Forms a hexadecamer with nsp7 (8 subunits of each) that may participate in viral replication by acting as a primase. Alternatively, may synthesize substantially longer products than oligonucleotide primers. {ECO:0000269|PubMed:22039154}.; FUNCTION: [Non-structural protein 9]: Plays an essential role in viral replication by forming a homodimer that binds single-stranded RNA. {ECO:0000269|PubMed:19153232}.; FUNCTION: [Non-structural protein 10]: Plays a pivotal role in viral transcription by stimulating both nsp14 3'-5' exoribonuclease and nsp16 2'-O-methyltransferase activities. Therefore plays an essential role in viral mRNAs cap methylation. {ECO:0000269|PubMed:22022266, ECO:0000269|PubMed:22635272}.; FUNCTION: [RNA-directed RNA polymerase nsp12]: Responsible for replication and transcription of the viral RNA genome. {ECO:0000269|PubMed:22791111}.; FUNCTION: [Helicase nsp13]: Multi-functional protein with a zinc-binding domain in N-terminus displaying RNA and DNA duplex-unwinding activities with 5' to 3' polarity. Activity of helicase is dependent on magnesium. {ECO:0000269|PubMed:12917423, ECO:0000269|PubMed:22615777}.; FUNCTION: [Proofreading exoribonuclease nsp14]: Enzyme possessing two different activities: an exoribonuclease activity acting on both ssRNA and dsRNA in a 3' to 5' direction and a N7-guanine methyltransferase activity (PubMed:16549795, PubMed:20421945, PubMed:22635272). Acts as a proofreading exoribonuclease for RNA replication, thereby lowering The sensitivity of the virus to RNA mutagens (PubMed:23966862, PubMed:29511076, PubMed:21593585). {ECO:0000269|PubMed:16549795, ECO:0000269|PubMed:20421945, ECO:0000269|PubMed:21593585, ECO:0000269|PubMed:22635272, ECO:0000269|PubMed:23966862, ECO:0000269|PubMed:29511076}.; FUNCTION: [Uridylate-specific endoribonuclease nsp15]: Plays a role in viral transcription/replication and prevents the simultaneous activation of host cell dsRNA sensors, such as MDA5/IFIH1, OAS, and PKR (PubMed:28158275, PubMed:18045871). Acts by degrading the 5'-polyuridines generated during replication of the poly(A) region of viral genomic and subgenomic RNAs. Catalyzes a two-step reaction in which a 2'3'-cyclic phosphate (2'3'-cP) is first generated by 2'-O transesterification, which is then hydrolyzed to a 3'-phosphate (3'-P) (PubMed:16828802). If not degraded, poly(U) RNA would hybridize with poly(A) RNA tails and activate host dsRNA sensors (PubMed:28158275, PubMed:18045871). {ECO:0000269|PubMed:16828802, ECO:0000269|PubMed:18045871, ECO:0000269|PubMed:28158275}.; FUNCTION: [2'-O-methyltransferase nsp16]: Methyltransferase that mediates mRNA cap 2'-O-ribose methylation to the 5'-cap structure of viral mRNAs (PubMed:18417574, PubMed:22022266,PubMed:20421945). N7-methyl guanosine cap is a prerequisite for binding of nsp16 (PubMed:18417574). Therefore plays an essential role in viral mRNAs cap methylation which is essential to evade immune system (PubMed:18417574, PubMed:22022266,PubMed:20421945). {ECO:0000269|PubMed:18417574, ECO:0000269|PubMed:20421945, ECO:0000269|PubMed:22022266, ECO:0000305}.
