Figure 4
Ribbon representation of the three KH3 domains in the asymmetric unit (coloured red, yellow and green) and an omit map showing the electron density around the single-stranded DNA drawn at the 1σ level. Only two of the KH3 domains (red, yellow) interact with the DNA. The third KH3 domain (green) interacts with the second (yellow) via the strand β1 edges of their respective β-sheets, an interaction also seen in crystals of the uncomplexed protein (Backe et al., 2004).
