Actually this is Tivilee. I am wondering if a protein has no helicase motif and does not belong to any of the subclasses, can it still unwind DNA and be considered to have helicase activity? Functionally it unwinds in the 3' to 5' direction. We are wondering whether it can be a contaminant or real helicase if it has no helicase domains? thanks for help.
