| Research Abstract |
The nucleocapsid proteins(NP) of Tomato Spotted Wilt Virus(TSWV) are key proteins in the replication of viral RNA. In this study, we obtained crystals of recombinant TSWV NPs diffracting to 2. 7Åresolution. The asymmetric unit contains three NP molecules forming trimeric ring-like structure. Moreover, the inside of TSWV NP trimeric ring shows the positive charge rich surface, suggesting that these regions are expected to be genomic RNA binding site.
