Figure 3
A sequence alignment of putative DAD enzymes. The secondary structure of the Alcaligenes sp. 4HAP enzyme is shown below the sequences. The amino-acid residues are colour-coded as follows: cyan, basic; red, acidic; green, neutral polar; pink, bulky hydrophobic; white, Gly, Ala and Pro; yellow, Cys. The iron-binding histidine residues are indicated with asterisks, which also conveniently mark the two cupin motifs (Dunwell et al., 2004BB13). Numbering refers to the combined alignment.
