LITERATURE
purified recombinant enzyme complexes Trm7-Trm734 and Trm7-Trm734-SAM, hanging drop vapor diffusion technique, mixing of 3 mg/ml protein solution with reservoir solution containing 0.1 M HEPES-NaOH, pH 7.5, 2 M (NH4)2SO4, 2% PEG 400, 2 mM phenol, and 3% ethylene-glycol, and equilibration against 0.2m ml reservoir solution, soaking of the crystals in in the mother liquor containing 1 mM SAM for complex 2, 20°C, 5 days, X-ray diffraction structure determination and analysis at 2.32-3.20 A resolution
