Sample preparation
Crystal | Density Matthews: 2.06 Å3/Da / Density % sol: 40.37 % |

Crystal grow | Temperature: 298 K / Method: vapor diffusion, hanging drop Details: Crystals formed by mixing 1:1 ratio of 13.3 mg/mL protein solution with well solution containing 100 mM 4-(2-Hydroxyethyl)-1-piperazinepropanesulfonic acid (HEPPS) pH 8.5 and 22% (w/v) PEG ...Details: Crystals formed by mixing 1:1 ratio of 13.3 mg/mL protein solution with well solution containing 100 mM 4-(2-Hydroxyethyl)-1-piperazinepropanesulfonic acid (HEPPS) pH 8.5 and 22% (w/v) PEG 8K. 1 mM adenine and 50 mM Sodium/Potassium Phosphate pH 7.0 were added to protein prior to mixing with well solution. Substrates were captured in lattice prior to freezing by soaking crystals in 20% (w/v) ethylene glycol, 100 mM HEPPS pH 8.5, 22% (w/v) PEG 8K, 25 mM sodium/potassium phosophate pH 7.0, 1 mM nicotinic acid mononucleotide, and 1 mM adenine for 30 minutes. Crystals were then soaked in the same solution, but with 30% PEG 8K instead of 20% ethylene glycol and 20% PEG 8K |
