Haloalkane dehalogenases are key enzymes for the degradation of halogenated aliphatic pollutants. The haloalkane dehalogenase DbjA constitutes a novel substrate-specificity class with high catalytic activity for β-methylated haloalkanes. In order to reveal the mechanism of its substrate specificity, DbjA has been crystallized using the hanging-drop vapour-diffusion method. The best crystals were obtained using the microseeding technique with a reservoir solution consisting of 17-19.5%(w/v) PEG 4000, 0.2 M calcium acetate and 0.1 M Tris-HCl pH 7.7-8.0. The space group of the DbjA crystal is P212 12, with unit-cell parameters a = 212.9, b = 117.8, c = 55.8 Å. The crystal diffracts to 1.75 Å resolution.
