Figure 4. Model of the 933W repressor-operator complex.

Figure 4

(A) 933W repressor in complex with the 933W consensus DNA site. The complex is oriented looking down the C-terminal portion of the DNA contacting (“recognition") to the N-terminal portions. The identity of the putative DNA contacting residues is indicated and highlighted in purple. The DNA is modeled on the right with the “top" strand (see Figure 1C) shown in grey and the complementary strand in black. (B) Schematic representation of the contacts identified from the model built structure between residues in the recognition helix of 933W repressor and bases in the 933W consensus half site DNA sequence. Predicted interactions are depicted by arrows.
