Description:
Orotate phosphoribosyltransferase (OPRT) catalyzes the Mg2+-dependent condensation of orotic acid (OA) with 5-α-D-phosphorylribose 1-diphosphate (PRPP) to yield diphosphate (PPi) and the nucleotide orotidine 5′-monophosphate. OPRT fromPlasmodium falciparumproduced inEscherichia coliwas crystallized by the sitting-drop vapour-diffusion method in complex with OA and PRPP in the presence of Mg2+. The crystal exhibited tetragonal symmetry, belonging to space groupP41orP43, with unit-cell parametersa=b= 49.15,c = 226.94 Å. X-ray diffraction data were collected to 2.5 Å resolution at 100 K using a synchrotron-radiation source.
