ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	7.7	288	THE ENZYME WAS DIALYSED IN 30 MM NAK-PHOSPHATE BUFFER, PH=8.0. SINGLE CRYSTALS WERE GROWN AT 15C WITHIN A FEW WEEKS IN HANGING DROPS (10-15 ML EACH) INITIALLY CONTAINING 1.25 M NAK-PHOSPHATE (PH=8.0), 100 MM 3-PG, 25 MM MGCL2, 20 MM ADP, 10 MM DITHIOTHREITOL, 0.02% NAN3 AND 15 MG/ML PGK. RESERVOIR SOLUTIONS CONTAINED 2.4-2.75 M NAK-PHOSPHATE(PH=8.0)., pH 7.70
