Crystallization Details

Method	pH	Temprature	Details
X-RAY DIFFRACTION	7.4	277	Freshly purified aromatase in 100mM potassium phosphate buffer, pH 7.4, containing 20% glycerol, 0.1mM androstenedione, and 1mM n-dodecyl-D-maltopyranoside (BDM) was mixed with reservoir cocktails of 24 to 30% polyethylene glycol 4000 and 0.5M NaCl in 0.05M Tris-HCl buffer pH 8.5 and vapor diffused in sealed 24-well sitting drop plates against corresponding reservoir solution. The purification and crystallization experiments were all conducted at 4 C. Reddish-brown color hexagonal rod-shaped crystals appeared in 7-10 days and continued to grow up to 14-16 days, VAPOR DIFFUSION, temperature 277K
