Functions of the Head and Tail regions of NrS-1 polymerase. (A) Assembly of NrS-1 CTR hexamer. Cartoon and surface presentations of the Head and Tail region are shown on the right. (B) Relative orientations of the Head, helicase domain, and Tail within the monomer of NrS-1 CTR. L1 and L2 linkers are colored in magenta and black, respectively. (C) In vitro DNA binding by truncated NrS-1 N392 and NrS-1 N618 mutants. (D) In vitro DNA-unwinding assays catalyzed by the full-length or truncated NrS-1 polymerase. (E) DNA polymerization assays catalyzed by NrS-1 N392 and NrS-1 N618. (F) Comparison of P1 and P2 products generated by the full-length and truncated NrS-1 polymerase.
