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
