Figure 3.
Structure of TTERecR16-196. Molecular surface of full-length TTERecR (A) and TTERecR16-196 (B) viewed in the same orientations. Electrostatic potential is indicated by different colours: blue is basic; red is acidic. (C) The structure of TTERecR N-N dimer (monomer A is green, monomer B is palegreen) is shown as a cartoon diagram. Expanded view of the circle, helix α1 of monomer B (palegreen) interacts with helix α3 and the zinc finger motif of monomer A (green). Interacting residues are shown as sticks. (D) The structure of the TTERecR16-196 N-N dimer (monomer A is purple, monomer B is light pink). (E) Superimposed structures of TTERecR16-196 N-N dimer (purple) and TTERecR N-N dimer (green). (F) Superimposed structures of the TTERecR16-196 monomer (purple) and TTERecR monomer (green). (G) Size-exclusion chromatography analysis of the interaction between TTERecR16-196 and TTERecO; TTERecR and TTERecO. (H) Hydrophobic patch (marked with a circle in Figure 3A) is formed by the hydrophobic loop06-121 and HhH domain of full-length TTERecR. The hydrophobic residues are shown as sticks.
