摘要：

The pyridoxal phosphate-dependent enzyme dialkylglycine decarboxylase (E.C. 4.1.1.64) has been crystallized by vapor diffusion from a 15% polyethyleneglycol solution with sodium pyruvate as coprecipitant. The space group of the crystals is either P6222 or the enantiomorph, P6422, with one subunit of 46,500 Da per asymmetric unit. The unit cell has dimensions a = b = 152·7 A ̊, c = 86·6 A ̊, α = β = 90 °, γ = 120 °, and a solvent content of approximately 61%. Diffraction extends to 2·3 Å resolution. © 1991.
