The smaller one contains the methyltransferase domain and the helicase domain (Hel). This core helicase domain consists of two RecA domains and an N-terminal accessory domain (this entry) containing a flexible loop, a long alpha-helix and an antiparallel, six-stranded beta-sheet. This N-terminal domain plays a role in the binding of the host factors TOM1 and ARL8 required for viral replication [1,2]. It is also found in proteins from related virus.

The (+) RNA virus helicase core contains two RecA-like alpha/beta domains. The N-terminal ATP-binding domain contains a parallel six-stranded alpha-sheet surrounded by four helices on one side and two helices on the other. The C-terminal domain contains a parallel four-stranded beta-sheet sandwiched between two helices on each of its sides. The (+) RNA virus helicase core is likely to bind NTP in cleft between the N terminus of the ATP-binding domain and the beginning of the C-terminal domain [2,5]. Helicase activity for this domain has been demonstrated [1]. This helicase has multiple roles at different stages of viral RNA replication, as dissected by mutational analysis [3].
