This is the N-terminal zinc finger domain present in reverse gyrase proteins. Most reverse gyrases have a conserve the N-terminal zinc finger domain adopting a treble clef fold, suggesting the importance of this domain domain for the proteins function. In addition, these proteins contain a second zinc finger of zinc beta-ribbon type that is grafted into the Toprim domain (Pfam:PF01751). Deletion of both zinc fingers abolishes supercoiling activity of reverse gyrase. The structure of Thermotoga maritima reverse gyrase shows that the N-terminal zinc finger firmly attaches the H1 (helicase 1) domain to the topoisomerase domain contributing to double-strand DNA (dsDNA) binding [1].

Members of this family include the DEAD and DEAH box helicases. Helicases are involved in unwinding nucleic acids. The DEAD box helicases are involved in various aspects of RNA metabolism, including nuclear transcription, pre mRNA splicing, ribosome biogenesis, nucleocytoplasmic transport, translation, RNA decay and organellar gene expression.
