Figure 2 Comparison of GBD with a zinc finger. (A) Superposition of the backbones of 46 GBD structures, Lys145-Val206, in the absence of the DNA refined by simulated annealing. Different colors are used for indicating the secondary structural elements. The N- and C-termini are labeled. (B) A diagrammatic drawing of the final structure made by energy minimization of the mean co-ordinates of the ensemble shown in (A), superimposed on a presentation of electropolarization. Positive charges are shown in blue and negative charges in red. The side that recognizes DNA is indicated with an arrow. (C) The 3D structure and electropolarization of the first zinc finger of SWI5 (Protein Data Bank code 1NCS) shown in the same way as in (B).
