Structures of the type I and type II crystals of CARDO-RJ3. (a) Type I overall structure shown in cartoon presentation. The Fd domain is coloured red, the FAD-binding domain is in yellow and the NADH-binding domain is in blue. Bound FAD (green sticks) and the [2Fe–2S] cluster (brown and yellow spheres) are also shown. (b) Type II overall structure shown in the same manner as the type I structure (Fd domain, salmon; FAD-binding domain, wheat; NADH-binding domain, slate). The [2Fe–2S] cluster is shown as brown and yellow spheres. His tags at the N-termini of molecules are shown in grey. All molecular graphics in this paper were prepared using PyMOL (DeLano, 2002). |
