1 Protein homooligomer Homooligomer Protein × 4 PDB declaration: tetrameric(4) Consistent with protein copy count Chain A; UniProt 21–148 Mutation:M13F, G116F TRS 2-AMINO-2-HYDROXYMETHYL-PROPANE-1,3-DIOL × 4 CU COPPER (II) ION × 8 CL CHLORIDE ION × 4 X-RAY DIFFRACTION X-ray crystallization conditions:VAPOR DIFFUSION, HANGING DROP;277 K;The 1.4 mM apo-protein was prepared in 100 mM pH=5.6 NaOAc buffer. For each well, add 300 uL reservoir buffer containing 100 mM pH=8.0 Tris-HCl, 10 mM CuSO4 and 20% PEG-4000. 3 uL of protein stock was mixed with 1 uL reservoir buffer on the glass slides and sealed on the wells. Diamond-shaped blue crystals grew within 4 days. Resolution 1.47 Å R-free 0.237
