1VAPOR DIFFUSION, SITTING DROP293The initial crystals of PUF1 were observed from a screen condition containing 25% PEG3350, 0.1 M Bis-Tris pH 5.5 with trypsin added to 3.53 mg/mL PUF1 at a 1:100 mass ratio. Further optimization was performed to obtain better crystals that formed in 25% PEG3350, 0.1M Bis-Tris pH 5.0, and 20% glycerol with streak seeding, trypsin at 0.06 mg/mL and PUF1 at 6.64mg/mL
