1	VAPOR DIFFUSION, HANGING DROP	7.2	298	Crystals were grown by the hanging-drop method. The drops contained 5 microlitres of 15mg/ml protein, a 20-fold molar excess of methyl-alpha-d-galactose in phosphate buffer pH 7.2 and 2ml of 35%(w/v) PEG 4000. 1ml of 35%(w/v) PEG 4000 was used as the reservoir solution. , VAPOR DIFFUSION, HANGING DROP, temperature 298K
