| 1 | VAPOR DIFFUSION, HANGING DROP | 4.6 | 293 | 1 uL protein solution (10 mg/mL GmhA, 500 mM sodium chloride, 10 mM HEPES, pH 7.0) + crystallization solution (10% w/v PEG4000, 0.1 M sodium acetate, pH 4.6) suspended over 1.5 M ammonium sulfate. Once crystals were grown, 0.2 uL ligand solution (50 mM Mut148591, 50 mM HEPES, pH 7.5) was added to the drops and allowed to soak for 90 minutes. |
