5.5.1.26 | hanging-drop vapour-diffusion method. Crystals of a complex of the enzyme with the substrate nogalonic acid methyl ester, obtained using PEG 4000 as precipitant. The crystals are orthorhombic, space group I222, with unit-cell parameters a = 69.1, b = 72.0, c = 65.4 A. They diffract to 1.35 A resolution using synchrotron radiation |
