| Enzyme Function | FUNCTION: The non-structural protein 1 (nsp1) protein plays a role in the inhibition of host interferon and pro-inflammatory cytokines production. Suppresses host RELA/p65 activation by blocking NFKBIA phosphorylation (PubMed:28715653). Targets also the RLR pathway downstream of the IRF3 activation by targeting host CREBBP to proteasomal degradation (PubMed:26773386). {ECO:0000269|PubMed:26773386, ECO:0000269|PubMed:28715653}.; FUNCTION: The replicase polyprotein of coronaviruses is a multifunctional protein: it contains the activities necessary for the transcription of negative stranded RNA, leader RNA, subgenomic mRNAs and progeny virion RNA as well as proteinases responsible for the cleavage of the polyprotein into functional products.; FUNCTION: The papain-like proteinase 1 (PLP1) and papain-like proteinase 2 (PLP2) are responsible for the cleavages located at the N-terminus of the replicase polyprotein. In addition, PLP2 possesses a deubiquitinating/deISGylating activity and processes both 'Lys-48'- and 'Lys-63'-linked polyubiquitin chains from cellular substrates. PLP2 also antagonizes innate immune induction of type I interferon by blocking the nuclear translocation of host IRF-3 (By similarity). {ECO:0000250}.; FUNCTION: [3C-like proteinase]: Responsible for the majority of cleavages as it cleaves the C-terminus of replicase polyprotein at 11 sites. Recognizes substrates containing the core sequence [ILMVF]-Q-|-[SGACN]. Inhibited by the substrate-analog Cbz-Val-Asn-Ser-Thr-Leu-Gln-CMK. Also contains an ADP-ribose-1''-phosphate (ADRP)-binding function (By similarity). {ECO:0000255|PROSITE-ProRule:PRU00772}.; FUNCTION: The helicase which contains a zinc finger structure displays RNA and DNA duplex-unwinding activities with 5' to 3' polarity. ATPase activity is strongly stimulated by poly(U), poly(dT), poly(C), poly(dA), but not by poly(G) (By similarity). {ECO:0000250}.; FUNCTION: The exoribonuclease acts on both ssRNA and dsRNA in a 3' to 5' direction. {ECO:0000250}.; FUNCTION: Nsp7-nsp8 hexadecamer may possibly confer processivity to the polymerase, maybe by binding to dsRNA or by producing primers utilized by the latter. {ECO:0000250}.; FUNCTION: Nsp9 is a ssRNA-binding protein. {ECO:0000250}.; FUNCTION: [Uridylate-specific endoribonuclease]: Plays a role in viral transcription/replication and prevents the simultaneous activation of host cell dsRNA sensors, such as MDA5/IFIH1, OAS, and PKR (By similarity). 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) (By similarity). If not degraded, poly(U) RNA would hybridize with poly(A) RNA tails and activate host dsRNA sensors (By similarity). {ECO:0000250|UniProtKB:P0C6X7}. |
