1	VAPOR DIFFUSION, SITTING DROP		290	Bups122_opt3 screen: 100mM HEPES free acid / NaOH pH 7.4, 200mM ammonium acetate, 27% (w/V) PEG 3350: BupsA.00122.a.A1.PW28612 at 14.33mg/ml plus 1mM ZnCl2 and 10mM compound HGN-0961/BSI110840: soaked over night with reservoir and 25mM compound: cryo: 20% EG + soak buffer: tray 310506a10: puck bno0-4. The ligand description was generated from a smiles string using phenix elbow. The ligand structure was minimized using GAMESS with the 3-21G basis. Restraints were extracted using phenix.elbow
