| Abstract: | Green crystals of the hexameric catalase HPII from Escherichia coli have been obtained by the hanging-drop method. The crystals belong to the monoclinic space group P2 with a = 123 A, b = 132 A, c = 93 A, beta = 112.5 degrees. There are three subunits in the asymmetric unit. The crystals diffract at least to 3.2 A resolution and are suitable for further X-ray diffraction studies. |
