Figure 25.2.8.1 

A typical macromolecular kinemage, combining details with context in the interactive display, for a glucocorticoid receptor–DNA complex (PDB file 1GLU). This view looks down the recognition helix, with one of the 4-Cys Zn sites on the right. Two sequence-specific binding interactions are shown with partial `ball-and-stick' representation: the Arg–guanine double hydrogen bond and the hydrophobic packing of Val to thymine methyl. DNA bases are in gold and protein side chains in pink, while atom balls are colour-coded as N blue, O red, C green, S yellow and Zn grey. Context is provided by the Cα backbone for the protein and a virtual backbone for the DNA (using P, C4′ and C1′), with lines symbolizing the rest of the base pairs.
