5.6.2.3 | evolution | superfamilies 1 and 2 (SF1 and SF2) comprise the largest number of helicase families and members are involved in a wide array of cellular functions that require manipulation of DNA or RNA structures, the helicases belong to the AAA+ ATPases. Helicase superfamilies can also be subdivided into those that translocate along DNA and unwind in a 3'-5' direction, e.g., SF1A, or a 5'-3 direction, e.g., SF1B. SF1 and SF2 helicases can be identified based on evolutionary conservation of seven sequence motifs (I, Ia, II-VI) that are required for ATP binding/hydrolysis, nucleic acid binding, and/or translocation. SF1 and SF2 helicases include a conserved core helicase domain that is comprised of two subdomains that share similarity with RecA ATPase/recombinase enzyme family | Deinococcus radiodurans |
