1VAPOR DIFFUSION, HANGING DROP6293Purified holo-hOAT was buffer-exchanged into 100 mM MES, 200 mM NaCl, 100 uM PLP, pH 6.0 buffer, and then concentrated to ~6 mg/mL. The crystallization was performed via the hanging drop vapor diffusion method according to previously published conditions with 50 mM Tricine pH 7.8 substituted to 50 mM MES pH 6.0 buffer. The crystals grew at room temperature within three days and reached their maximum size in a week.
