1	VAPOR DIFFUSION, SITTING DROP	7.5	298	UBC2 and UEV1 were mixed in a 1:1 molar ratio to a final concentration of 6.6 mg mL-1 and incubated on ice for 30 min. Crystals were grown using a sitting drop method with a 1:1 ratio of protein to reservoir solution (0.1 M Bis-Tris propane, pH 7.5, 0.2 M sodium formate and 20% PEG) in the drop. Crystals took 2 days to appear.
