Abstract:
Trypanosoma brucei ornithine decarboxylase, expressed and purified from E. coli, has been crystallized by the vapor diffusion method using PEG 3350 as a precipitant. The crystals belong to the monoclinic space group P2(1) and have cell constants of a = 66.3 angstroms, b = 151.8 angstroms, c = 83.7 angstroms, and beta = 101.2 degrees. While larger crystals are twinned, smaller crystals (0.4 x 0.3 x 0.05 mm3) are single.
