The NEDD4 and Ubiquitin Variant was mixed at molar ratio ~1:2, and then concentrated to 15mg/ml.
The protein sample was mixed with Trypsin at a 1:1000 (W/W) Trypsin:protein ratio before setting up crystallization.
Crystal was initially obtained from Molecular Dimentions Proplex screen condition E04.
Crystal used for structure refinement was grown in 20% PEG8000, 10% Glycerol, 0.1M HEPES pH 7.0 in hanging drop setup, using 1.5uL protein, 1.5uL well solution over 0.5 mL reservoir buffer at 20 C.
Crystals grow to mountable size in 4 days. Harvested crystal was flash-frozen in liquid nitrogen. 20% Glycerol was used as the cryo-protectant |
