| + | Classical swine fever virus (CSFV) is the ringleader of Classical swine fever (CSF). The non-structural protein 5B (NS5B) encodes an RNA-dependent RNA polymerase (RdRp) that is a key enzyme initiating viral RNA replication by a de novo mechanism. It is also an attractive target for the development of anti-CSFV drugs. To gain a better understanding on the mechanism of CSFV RNA synthesis, here we solved the first crystal structure of CSFV-NS5B. Our studies show that the CSFV-NS5B RdRp contains characteristic fingers, palm domain and thumb domain as well as a unique N-terminal domain (NTD) that had never been observed. Mutagenesis studies on NS5B validated the importance of NTD in the catalytic activity of this novel RNA-dependent RNA polymerase. Moreover, our results shed light on the understanding of CSFV infection.IMPORTANCE Pigs are important domestic animal. However, a highly contagious viral disease named Classical swine fever (CSF) causes devastating economic losses. Classical swine fever virus (CSFV) is the primary culprit of CSF, which is a positive-sense single-stranded RNA virus belonging to the Pestivirus genus, Flaviviridae family. Genome replication of CSFV depends on RNA-dependent RNA polymerase known as NS5B. However, the structure of CSFV-NS5B has never been reported, and the mechanism of CSFV replication is poorly understood. Here, we solved the first crystal structure of CSFV-NS5B, analyzed the function of characteristic fingers, palm, and thumb domains. Additionally, our structure also revealed the presence of a novel N-terminal domain (NTD). Biochemical studies demonstrated that the NTD of CSFV-NS5B is very important for RNA-dependent RNA polymerase (RdRp) activity. Collectively, our studies provide a structural basis for future rational design of anti-CSFV drugs which is critically important as no effective anti-CSFV drugs have been developed. | ||
