1	VAPOR DIFFUSION, HANGING DROP	7.5	298	Protein crystals of the SusG-D498N mutant were obtained via hanging drop vapor diffusion by mixing the protein (A280 = 15) with 10 mM alpha-D-glucosyl-maltotriosyl-maltotriose (O-GMH, Megazyme) against a crystallization liquor containing 18-20% PEG 4K, 100 mM HEPES pH 7.5, and 70 mM calcium acetate.
