Crystal grow | Temperature: 298 K / Method: vapor diffusion, sitting drop Details: Protein was dialyzed into 20 mM MES (pH 6.5) with 50 mM NaCl. Complex was formed by incubating the protein at 5 mg/mL with 2 mM dAMP and 5 mM MnCl2. 0.3 uL protein complex at 5 mg/ml TREX1 ...Details: Protein was dialyzed into 20 mM MES (pH 6.5) with 50 mM NaCl. Complex was formed by incubating the protein at 5 mg/mL with 2 mM dAMP and 5 mM MnCl2. 0.3 uL protein complex at 5 mg/ml TREX1 was mixed with an equal volume of reservoir solution and placed on a bridge above 50 uL of the reservoir solution. mTREX1-dAMP crystals grew in initial conditions of 0.2 M MES monohydrate, sodium hydroxide (pH 6.2), and 20% w/v polyethylene glycol 4,000. All crystals grew within one week. After crystal formation, 4 mM TIM009 was soaked into mTREX1-dAMP crystals for 5 days. Prior to data collection crystals were dipped into reservoir solution containing 15% glycerol in preparation for cryo-cooling |
