1 | VAPOR DIFFUSION, HANGING DROP | 4.6 | 298 | The protein (about 5 mg/mL) was preincubated with the inhibitor (dissolved in dimethylsulfoxide) at a molar ratio of 1:5. Crystals were grown from 0.1 m sodium acetate buffer, pH 4.6 and 2M NaCl as precipitant. Crystals were cryo-cooled in liquid nitrogen after soaking in 30% glycerol to prevent freezing. |
