title: Crystallization and preliminary x-ray investigation of thymidine phosphorylase from Escherichia coli.
abstract: 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.
