1	VAPOR DIFFUSION, HANGING DROP	6.5	293	Crystals was generated by pre-incubating the L3MBTL1 (12MG/ML IN 50MM KCL, 25MM TRIS-HCL PH 8.0, 1MM DTT) with a five-fold molar excess of monomethyl-lysine amino acid. Drops were prepared by mixing equal volumes of the complex with reservoir solution (7.5% PEG10K, 0.1 M Tris-maleate pH 6.5, 0.1 M ammonium sulfate), VAPOR DIFFUSION, HANGING DROP, temperature 293K
