Sf1 and sf2 helicases: family matters
WebThe Families of the SF1 and SF2 helicases Schematic, unrooted cladogram showing the three identified families of the SF1 (right), and the 9 families and one group of the SF2 (left). A comprehensive list of proteins in each family in human, S.cerevisiae, and E.coli is given in the Supplementary Tables ST1 and ST2. WebSF1 and SF2 helicases contain tandem RecA-like folds on a single polypeptide [2,3], while SF3-6 helicases assemble into toroidal ring-like structures from six RecA-like monomers (Figure 1B and 1C). In each case, the interface between the RecA-like domains form a cleft that is lined with conserved amino acids that coordinate NTP, Mg, and nucleic acid …
