title: Crystallization and preliminary X-ray crystallographic studies of Trypanosoma brucei prostaglandin F(2 alpha) synthase.
abstract: Prostaglandin F(2 alpha) is a potent mediator of various physiological and pathological processes. Trypanosoma brucei prostaglandin F(2 alpha) synthase (TbPGFS) catalyzes the NADPH-dependent reduction of 9,11-endoperoxide PGH(2) to PGF(2 alpha), and could thus be involved in the elevation of the PGF(2 alpha) concentration during African trypanosomiasis. In the present report, the purification and crystallization of recombinant TbPGFS are described. The active recombinant enzyme was crystallized by the hanging-drop vapor-diffusion meth-od using ammonium sulfate as a precipitant. The crystal belonged to a tetragonal space group, P4(1)2(1)2 or P4(3)2(1)2, with unit-cell parameters of a = b = 112.3 A, and c = 140.0 A. Native data up to 2.6 A resolution were collected from the crystal using our home facility.
