X-RAY DIFFRACTION	6.0	277	CRYSTALS OF ATGPA1 WERE GROWN AT 4 DEGREES CELSIUS USING THE HANGING-DROP VAPOR-DIFFUSION METHOD. DROPS CONTAINED 1.5 UL OF PROTEIN SOLUTION (20 MG/ML ATGPA1 IN 25 MM TRIS-HCL, PH 7.4, 5% (V/V) GLYCEROL, 150 MM SODIUM CHLORIDE, 1 MM DTT, 500 UL GTP-GAMMA-S) AND WERE EQUILIBRATED AGAINST 1.5 UL OF 0.3 M MAGNESIUM SULFATE, 0.1 M SODIUM CACODYLATE, PH 6.0, 21% (W/V) PEG 8000. INITIALLY OBTAINED CRYSTALS WERE USED FOR MACROSEEDING. CRYSTALS REACHED THEIR FINAL ROD-SHAPE FORM WITHIN 14 DAYS AFTER MACROSEEDING AND WERE CRYOPROTECTED IN THE MOTHER LIQUOR WITH 8% (V/V) GLYCEROL.
