The polypeptide chain of a TBSV subunit folds into two domains, connected by a hinge, and a flexibly-linked N-terminal arm. Sixty of the 180 N-terminal arms inter-digitate in groups of three, in an unexpected mode of protein association. The remaining 120 arms are not uniquely positioned with respect to the rest of the subunit. RNA is also not uniquely fixed to sites on the major domains.
番茄黑环病毒（TBSV）亚基的多肽链折叠成两个结构域，由一个铰链连接，并带有一个灵活连接的N端臂。180个N端臂中的60个以三个一组的方式相互交错，形成一种意想不到的蛋白质缔合模式。其余120个臂相对于亚基的其余部分没有独特的定位。RNA也没有唯一固定在主要结构域的位点上。
