Figure 3.
Ribbon representation of (A) LlaGI-DNA complex at 7.4 Å resolution and (B) LlaGIΔN-DNA complex at 2.8 Å resolution. The six structural domains are coloured distinctly. The nuclease is coloured brown, the N-core of the ATPase domain is coloured green, the C-core is in blue, the coupler in beige, the MTase domain in orange and the TRD in cyan. (C) The superposition of the Cα-trace of LlaGI at 7.4 Å and LlaBIII (PDB ID: 4XQK) reveals domain movement. LlaGI was superposed on to LlaBIII with respect to the coupler using Coot (27).
