Autocatalytic processing of the potyvirus helper component proteinase in Escherichia coli and in vitro.

abstract：:The type I interferon (IFN) response is part of the first-line defense against viral infection. To initiate replication, viruses have developed powerful evasion strategies to counteract host IFN responses. In the present study, we found that the Japanese encephalitis virus (JEV) NS5 protein could inhibit double-strand...
