|---|---|---|---|---|---|---|
| 1 | Protein–DNA Heteromer Protein × 2 DNA 2 PDB declaration: tetrameric(4) Consistent with all polymer counts | Chain A; UniProt 1–704 | Mutation:Residues 5 and 7 mutated to Ala | DNA Primer × 1 DNA Template × 1 thioredoxin 1 × 1 (P0AA25) | X-RAY DIFFRACTION X-ray crystallization conditions:VAPOR DIFFUSION, HANGING DROP;pH 7.5;273 K;A complex of 1x10^-4 M T7 DNA polymerase 5A7A:thioredoxin was assembled with an equimolar amount of double stranded DNA substrate. Crystallization was achieved using a buffer containing 50mM HEPES pH 7.5, 10mM MgCl_2, 2mM DTT, and 0.5 mM terminal ddTTP Seed crystals were grown by hanging drop vapor diffusion by mixing 1ul each of protein-DNA solution and a reservoir solutions containing between 16 to 20% PEG 8000, 100mM ACES pH 7.5, 120 ammonium sulfate, 30mM MgCl2, and 5mM DTT. These crystals were used to streak-seed a grid of protein/reservoir solutions with concentrations of PEG 8000 between 13 to 15%. Pyramidal crystals appeared overnight and reached a maximum size of ~150 X 150 X 100 um3 after 3 to 4 days. Crystals were harvested overnight in mother-liquor containing 10 % PEG 400, temperature 273K, VAPOR DIFFUSION, HANGING DROP | Resolution 2.60 Å R-free 0.284 |
