X-RAY DIFFRACTION	7.50	?	THE RAT SYNAPTOTAGMIN IV C2B DOMAIN WAS CRYSTALLIZED BY THE VAPOR DIFFUSION METHOD (HANGING DROP) BY MIXING 1 MICROLITER PROTEIN (IN 20 MM MES, 150 MM NACL AND 1 MM EDTA, PH 6.32) WITH 1 MICROLITER RESERVOIR SOLUTION (2.5M NACL, 0.1M CACL2, 0.1M HEPES, PH 7.5) SUSPENDED OVER 500 MICROLITERS RESERVOIR SOLUTION. HEXAGONAL CRYSTALS APPEARED OVERNIGHT AND GREW TO A FINAL SIZE OF 0.1 X 0.1 X 0.2 MM WITHIN TWO DAYS. PRIOR TO DATA COLLECTION, CRYSTALS WERE TRANSFERRED INTO CRYSTALLIZATION SOLUTION CONTAINING 20% (V/V) ETHYLENE GLYCOL FOR CRYSTALS GROWN IN 0.1 M CACL2, AND THEN COOLED IN LIQUID PROPANE.
