In addition to its proteolytic activity, it binds to viral RNA, and thus influences viral genome replication. RNA and substrate bind co-operatively to the protease (By similarity).[SAAS:SAAS000199_004_042266] RNA-directed RNA polymerase 3D-POL replicates genomic and antigenomic RNA by recognizing replications specific signals (By similarity).[SAAS:SAAS000199_004_010047] Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMed Genome replication in picornaviruses is catalyzed by a virally encoded RNA-dependent RNA polymerase, termed 3D. The enzyme performs this operation, together with other viral and probably host proteins, in the cytoplasm of their host cells. The crystal structure of the 3D polymerase of foot-and-mouth disease virus, one of the most important animal pathogens, has been determined unliganded and bound to a template-primer RNA decanucleotide. The enzyme folds in the characteristic fingers, palm and thumb subdomains, with the presence of an NH2-terminal segment that encircles the active site. In the complex, several conserved amino acid side chains bind to the template-primer, likely mediating the initiation of RNA synthesis. The structure provides essential information for studies on RNA replication and the design of antiviral compounds.
