Overall structure of BcGDHγα. (a) Overall structure of BcGDHγα shown as cartoon (left) and surface (right) models. In the cartoon model, the γ-subunit is shown as red α-helices and green loop regions, and the α-subunit is represented with blue α-helices, yellow β-strands and gray loop regions. In the surface model, the γ- and α-subunits are shown in red and blue, respectively, and are tightly bound to each other. The bound FAD is represented as an orange stick model. The cysteine cluster indicated with a red circle includes the iron–sulfur cluster shown as spheres. (b) A view of the model rotated 180° around the x axis. |
