1VAPOR DIFFUSION, SITTING DROP6.52932 microL of mother liquor to 2 microL of 12 mg/ml FAD domain. Crystals were obtained using a well solution of 28% polyethylene glycol 8000, 0.3 M ammonium sulfate, cacodylate buffer pH 6.5. Crystals of dimensions 70 x 70 x 900 M formed after 4-7 days. In order to form a coenzyme complex with NADP+, C773A/C999A FAD domain crystals were soaked in a 10 mM NADP+ solution for 10 minutes., VAPOR DIFFUSION, SITTING DROP, temperature 293K
