pH 6.5
Temperature 293.0
Details Final data were collected on a crystal obtained from crystallization conditions containing 30% polyethylene glycol (PEG) 10K, 0.1 M cacodylate pH 6.5 and 0.2 M ammonium sulfate, which had grown to a size of 0.2x0.1x0.1 mm3 over 7.5 months. 15% glycerol was used as a cryo-protectant, VAPOR DIFFUSION, HANGING DROP, temperature 293K
