1VAPOR DIFFUSION, SITTING DROP293Selenomethionine-derivatized promirolysin crystals were obtained at 20 degrees from drops containing 200 nL of protein solution at 0.6 mg/mL in 5 mM Tris-HCl pH 8.0, 50 mM sodium chloride and 100 nL of reservoir solution, which comprised 25% PEG 1500, 0.1 M MIB buffer (malonic acid, imidazole and boric acid at a 2:3:3 molar ratio), pH 6.0.
