FIGURE 1.

Ribbon representation of the dimer association of DlADH (PDB ID: 1SBY). Secondary structure nomenclature is as suggested in the publication of the x-ray structure (10) and is shown for one of the subunits. Amino acids lining the R1 and R2 pockets of the active site are shown by the green and blue stick models, respectively. The color coding of secondary structures is red for α-helices, aquamarine for β-strands, magenta for 3–10 helices (γ), and blue for loops. The designation of the active site pockets was followed from the description of crystallographic studies by Benach (11).
