1 Protein heterocomplex Heteromer Protein × 3 PDB declaration: trimeric(3) Consistent with protein copy count Chain A; UniProt 1–175 Chain B; UniProt 176–277 Mutation:D9A,D28A Mutation:T245D AC-ASP-GLU-VAL-ASP-CMK × 1 AZI AZIDE ION × 1 X-RAY DIFFRACTION X-ray crystallization conditions:VAPOR DIFFUSION, HANGING DROP;291 K;Crystals were obtained at 18 C by the hanging drop vapor diffusion method using 4 mL drops that contained equal volumes of protein and reservoir solutions over a 0.5 mL solution of 100 mM sodium citrate, pH 4.9-5.2, 8-18 % PEG 6000 (w/v), 10 mM DTT, and 3 mM NaN3. Crystals appeared within 3-5 days and were briefly immersed in a cryogenic solution containing 10% MPD (2-methylpentane-2,4-diol) and 90% reservoir solution. Resolution 1.87 Å R-free 0.190
