Abstract:
TATA box-binding protein (TBP) from Methanococcus jannaschii has been crystallized by the hanging-drop vapour-diffusion method using PEG MME 2000 as a precipitant. The crystal belongs to space group P21, with unit-cell parameters a = 53.2, b = 55.5, c = 123.4 A,a = 90.0, fi = 91.0, y = 90.0 degrees, and contains four molecules in the asymmetric unit. A data set was collected to 1.9 A resolution using synchrotron radiation. A molecular-replacement solution was found using the structure of TBP from Sulfolobus acidocaldarius as a model. Crystallographic refinement is in progress.
