THE NATIVE RECOMBINANT PGIS (25 REMARK 280 MG/ML IN THE GEL FILTRATION BUFFER CONTAINING 20 MM TRIS, PH 8.0 REMARK 280 AND 150 MM NACL) WAS FOUND TO CRYSTALLIZE SPONTANEOUSLY INTO REMARK 280 NEEDLE CLUSTERS IN THE EPPENDORF TUBE WHEN STORED AT 4 C FOR REMARK 280 ABOUT A WEEK. A COMBINATION OF MICROSEEDING TECHNIQUE AND THE REMARK 280 HANGING-DROP VAPOR-DIFFUSION METHOD WAS THEN USED TO IMPROVE REMARK 280 CRYSTAL QUALITY. SPECIFICALLY, SEED STOCK WAS PREPARED BY REMARK 280 CRUSHING THESE INITIAL PGIS NEEDLE CLUSTERS WITH THE SEED BEAD REMARK 280 KIT (HAMPTON RESEARCH). FOLLOWING FOUR 10-FOLD SERIAL DILUTIONS REMARK 280 OF THE SEED STOCK USING THE GEL FILTRATION BUFFER, 1 MICROLITER REMARK 280 OF DILUTED SEEDS WAS ADDED INTO A 10 MICROLITER DROP OF FRESHLY REMARK 280 CONCENTRATED PGIS SAMPLE, AND EQUILIBRATED AT 4 C AGAINST 450 REMARK 280 MICROLITER OF THE GEL FILTRATION BUFFER. CRYSTALLIZATION OF REMARK 280 HPGIS-MINOXIDIL COMPLEX: THE INHIBITOR-ENZYME COMPLEX WAS REMARK 280 PREPARED BY ADDING MINOXIDIL (FINAL CONCENTRATION 0.1 MM) TO A REMARK 280 20 MG/ML HPGIS STOCK SOLUTION. CRYSTALS OF THE COMPLEX WERE THEN REMARK 280 OBTAINED BY CO-CRYSTALLIZATION, WITH THE TECHNIQUE DESCRIBED REMARK 280 ABOVE USING LIGAND-FREE HPGIS MICROCRYSTALS AS SEEDS., VAPOR REMARK 280 DIFFUSION, HANGING DROP, TEMPERATURE 277K REMARK 290 REMARK 290 CRYSTALLOGRAPHIC SYMMETRY REMARK 290 SYMMETRY OPERATORS FOR SPACE GROUP: P 1 21 1 REMARK 290 REMARK 290 SYMOP SYMMETRY REMARK 290 NNNMMM OPERATOR REMARK 290 1555 X,Y,Z REMARK 290 2555 -X,Y+1/2,-Z REMARK 290 REMARK 290 WHERE NNN -> OPERATOR NUMBER REMARK 290 MMM -> TRANSLATION VECTOR REMARK 290 REMARK 290 CRYSTALLOGRAPHIC SYMMETRY TRANSFORMATIONS REMARK 290 THE FOLLOWING TRANSFORMATIONS OPERATE ON THE ATOM/HETATM REMARK 290 RECORDS IN THIS ENTRY TO PRODUCE CRYSTALLOGRAPHICALLY REMARK 290 RELATED MOLECULES.
