Tomato mosaic virus (ToMV) generates two large replication proteins in the host cell. 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.	Domain

This entry represents the (+) RNA virus helicase core domain. 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].	Domain
