[[https://www.uniprot.org/uniprot/POLG_SVM93 POLG_SVM93]] NTPase presumably plays a role in replication. Despite having similarities with helicases, does not seem to display any helicase activity (By similarity).  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).  Protease-polymerase processes the polyprotein: Pro-Pol is first released by autocleavage, then all other proteins are cleaved (By similarity).  Protease-polymerase is a RNA-directed RNA polymerase which replicates genomic and antigenomic viral RNA by recognizing specific signals. Catalyzes the covalent attachment VPg with viral RNAs (By similarity).  Capsid protein self assembles to form an icosahedral capsid with a T=3 symmetry, about 38 nm in diameter, and consisting of 180 capsid proteins. The capsid encapsulate the genomic RNA and VP2 proteins. Attaches virion to target cells, 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).
