Crystallization and preliminary x-ray investigation of thymidine phosphorylase from Escherichia coli.
Crystals of thymidine phosphorylase from Escherichia coli have been grown from solutions of ammonium sulfate. The crystals are tetragonal, space group P4(1)2(1)2 or P4(3)2(1)2; the axes are a = 132.0 (1) and c = 67.2 (1) A. The crystals are quite stable to x-rays and diffract beyond 2.6-A resolution. The molecule is a dimer and utilizes the 2-fold symmetry of the space group, resulting in one subunit per asymmetric unit.
