Figure 3. Stereoviews of the hTRF1 DNA-binding domain
structures. Backbone atoms and sidechain atoms are shown in
yellow and red, respectively; the N and C termini are marked.
(a) The best-fit superposition of the 18 structures; three
tryptophans and one phenylalanine residue form the hydrophobic
core. (b) The refined average structure again showing the amino
acids that form the hydrophobic core.
