| Enzyme Function | FUNCTION: NTPase presumably plays a role in replication. {ECO:0000250}.; FUNCTION: Viral genome-linked protein is covalently linked to the 5'-end of the positive-strand, negative-strand genomic RNAs and subgenomic RNA. Acts as a genome-linked replication primer. May recruit ribosome to viral RNA thereby promoting viral proteins translation (By similarity). {ECO:0000250}.; FUNCTION: 3C-like protease processes the polyprotein: 3CLpro-RdRp (p72) is first released by autocleavage, then all other proteins are cleaved. {ECO:0000250}.; FUNCTION: RNA-directed RNA polymerase replicates genomic and antigenomic RNA by recognizing replications specific signals. Transcribes also a subgenomic mRNA by initiating RNA synthesis internally on antigenomic RNA. This sgRNA codes for structural proteins. Catalyzes the covalent attachment VPg with viral RNAs (By similarity). {ECO:0000255|PROSITE-ProRule:PRU00539}.; FUNCTION: Capsid protein VP60 self assembles to form an icosahedral capsid with a T=3 symmetry, about 35 nm in diameter, and consisting of 180 capsid proteins. A smaller form of capsid with a diameter of 23 nm might be capsid proteins assembled as icosahedron with T=1 symmetry. The capsid encapsulate VP2 proteins and genomic or subgenomic RNA. Attaches virion to target cells by binding histo-blood group antigens, inducing endocytosis of the viral particle. Acidification of the endosome induces conformational change of capsid protein thereby injecting virus genomic RNA into host cytoplasm (By similarity). {ECO:0000250}. |

| Post Translational Modification | PTM: Specific enzymatic cleavages by its own cysteine protease yield mature proteins. The protease cleaves itself from the nascent polyprotein autocatalytically. Precursor p41 can be cleaved by viral 3CLpro into protein p19 and VPg, or cleaved by host protease into protein p23/2 and protein p18 (By similarity). {ECO:0000250}.; PTM: VPg is uridylylated by the polymerase and is covalently attached to the 5'-end of the polyadenylated genomic and subgenomic RNAs. This uridylylated form acts as a nucleotide-peptide primer for the polymerase (By similarity). {ECO:0000250}. |
