FIG. 3.

Space-filling model of predicted α-CTD structure. The model was based on the atomic coordinates of Jeon et al. (15). Colored residues are those identified as important at the Φ(rhaB-lacZ)Δ84 promoter fusion. Orange residues are those that may be involved in interaction with DNA (DNA-binding category), while violet residues are the residues that are unlikely to be involved in interaction with DNA (Other category). Residue numbers for some of the important residues are shown. The two models are related to one another by a 90° rotation around the vertical axis.
