Figure 3.
Non-conserved amino acids likely to interact with the DNA substrate. The Dbh amino acid sequence is shown with the domains indicated by color: palm (green), finger (blue), thumb (cyan), and LF (magenta). Non-conserved amino acids key to the interaction of Dbh and DNA duplex are highlighted in yellow. The secondary structures are indicated as coils (α-helices) and arrows (β-sheets) above the aligned primary amino acid sequence.
