For crystallisation, CYP199A4 was concentrated to approx. 40 mg mL-1 in 50 mM Tris buffer, pH 7.4. Crystals were obtained using the hanging-drop vapour diffusion method at 16 degrees C using 1.2 microlitres of protein with 1.2 microlitres of reservoir solution and equilibrated with 500 microlitres of the same reservoir solution. The crystallisation buffer was 100 mM Bis-Tris buffer (adjusted to pH 5.0-5.75 with acetic acid), 0.2 M magnesium acetate and 20-32% PEG 3350. |
