Viral (Superfamily 1) RNA helicase

Helicase activity for this family has been demonstrated [1] and NTPase activity [2]. This helicase has multiple roles at different stages of viral RNA replication, as dissected by mutational analysis [3]. This family is discussed pages 388-391. [1]. 8269709.

UvrD-helicase domain-containing protein

The Rep family helicases are composed of four structural domains. The Rep family function as dimers. REP helicases catalyse ATP dependent unwinding of double stranded DNA to single stranded DNA. Swiss:P23478, Swiss:P08394 have large insertions near to the carboxy-terminus relative to other members of the family. Structure of Swiss:P09980. [1]. 9288744.
