Figure 3. Stereoview of the superposition of
Anabaenathioredoxin-2 (orange) [Saarinen et al 1995] and a
monomer of AaFd4 (green), showing the similarity between the
folds. In addition to the similarity of the overall folds, two
of the [2Fe-2S] cysteine ligands, Cys9 and Cys22 (shown in a
darker shade of green), in AaFd4 are positioned near the two
active site cysteine residues of thioredoxin-2, Cys32 and Cys35
(shown in a darker shade of orange).
