Figure 2. Overall crystal structures of AtAcnX, TkAcnX, and mAcn (aconitase from bovine mitochondria).

Caption

These molecules commonly contain the indicated [Fe-S] cluster, and consist of four distinct domains 1 (yellow), 2 (green), 3 (blue), and 4 (red) and a linker region (black). The small subunit of TkAcnX corresponds to fragmented domain 4. In comparisons with AcnX, several large insertions in domains 1-4 of mAcn were colored in ocher, light-green, light-blue, and pink, respectively.
