1MICRODIALYSIS727810 mg/ml enzyme dialyzed against 50 mM ammonium N-[tris(hydroxylmethyl)methyl]2-aminoethane sulfonate (pH 6.7 at 25 deg C) with 1 mM NADH and 10 mM N-benzylformamide as the concentration of 2-methyl-2,4-pentanediol was raised to 25 %. Crystas was mounted on a fiber loop and flash vitrified by plunging it into liquid N2.
