Crystallization (Commentary)

EC Number Crystallization (Comment) Organism
4.3.1.17 hanging-drop vapor-diffusion method, crystal structures of the native and 1-aminocyclopropane-1-carboxylate-complexed enzyme. The crystals of native and Se-Met belong to the space group P3(2)21 with unit cell parameters of a=b= 122.3 A, c = 115.0 A, and gamma = 120°, and there are three molecules in an asymmetric unit. The crystals of the ACC complex belong to space group P1 with unit cell parameters of a = 105.8 A, b = 147.2 A, c = 149.0 A, a = 73.18, b = 90.18, and gamma = 68.48, and 24 molecules are included in an asymmetric cell Pyrococcus horikoshii
