X-RAY DIFFRACTION ? 293 The holoenzyme crystals were first grown via a hanging drop vapor diffusion method. Each drop contained 2 uL of protein and 2 uL of well solution. The best crystallization condition contained 8% PEG 6000, 100 mM NaCl, 5% glycerol, and 50 mM Tricine pH 7.8. Once the holoenzyme crystals reached their maximum size within five days, 1 uL of 10 mM 181 was added to the drop with crystals. Within the first three minutes of 181 addition, the hOAT crystals turned their color from yellow to transparent. The crystals were soaked for 44 minutes, transferred into cryoprotective solution (well solution supplemented with 30% glycerol), and then flash-frozen in liquid nitrogen.
