1.  Crystallization and preliminary crystallographic analysis of the ferredoxin component of carbazole 1,9a-dioxygenase from Nocardioides aromaticivorans IC177 
The ferredoxin component of carbazole 1,9a-dioxygenase from N. aromaticivorans IC177 was crystallized and diffraction data were collected to 2.0 Å resolution.
Carbazole 1,9a-dioxygenase (CARDO) catalyzes the dihydroxylation of carbazole by angular position (C9a) carbon bonding to the imino nitrogen and its adjacent C1 carbon. CARDO consists of a terminal oxygenase component and two electron-transfer components: ferredoxin and ferredoxin reductase. The ferredoxin component of carbazole 1,9a-dioxygenase from Nocardioides aromaticivorans IC177 was crystallized at 293 K using the hanging-drop vapour-diffusion method with ammonium sulfate as the precipitant. The crystals, which were improved by macroseeding, diffract to 2.0 Å resolution and belong to space group P41212.

2.  Crystallization and preliminary X-ray diffraction studies of the ferredoxin reductase component in the Rieske nonhaem iron oxygenase system carbazole 1,9a-dioxygenase 
The NAD(P)H:ferredoxin oxidoreductase in carbazole 1,9a-dioxygenase from Janthinobacterium sp. J3 was crystallized and diffraction data were collected to 2.60 Å resolution.
Carbazole 1,9a-dioxygenase (CARDO), which consists of an oxygenase component (CARDO-O) and the electron-transport components ferredoxin (CARDO-F) and ferredoxin reductase (CARDO-R), catalyzes dihydroxylation at the C1 and C9a positions of carbazole. CARDO-R was crystallized at 277 K using the hanging-drop vapour-diffusion method with the precipitant PEG 8000. Two crystal types (types I and II) were obtained. The type I crystal diffracted to a maximum resolution of 2.80 Å and belonged to space group P42212, with unit-cell parameters a = b = 158.7, c = 81.4 Å. The type II crystal was obtained in drops from which type I crystals had been removed; it diffracted to 2.60 Å resolution and belonged to the same space group, with unit-cell parameters a = b = 161.8, c = 79.5 Å.
