X-RAY DIFFRACTION 7.0 295 Human SMYD3 (1-428) with SAM in the SAM-binding site was concentrated to 11.7 mg/mL in 25 mM Tris-HCl pH 8 and 150 mM NaCl. Peptide (21st Century Biochemical) was solubilized in 100mM water. Two ul peptide was added to 200 ul of protein (five fold molar excess of peptide) and allowed to complex with the protein overnight at 4C. Crystals were obtained from a Hampton Index HT broad screen in sitting drops at 22C with condition H7 (0.15 DL-malic acid pH 7.0, 20% w/v PEG 3,350). Crystals were flash frozen in 20 percent ethylene glycol in well solution prior to data collection
