ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, SITTING DROP	4.6	295	Sa MtgA E100Q at 10 mg/ml was mixed with 1mM Moenomycin and 1mM MnCl2 and incubated on ice for ~3 hours. Precipitated material was removed by centrifugation at 16,000xg for 5 minutes. The Mmoenomycin complex was crystallized by hanging drop vapor diffusion, mixing the protein 1:1 with a reservoir solution containing 0.1M Na Acetate pH 4.6, 0.2M NaCl, 30% MPD at 22oC. Hexagonal plate crystals formed in 1 week., VAPOR DIFFUSION, SITTING DROP, temperature 295K
