Description:
Quinolinate phosphoribosyltransferase (QPRT), purified from hog liver, has been crystallized using PEG 8000 as the precipitant. The crystals form long hexagonal rods in the space group P6322 with cell dimensions a = b = 121.7, c = 94.5 Å. Based on the unit-cell dimensions and the calculated molecular mass of 33 500 Da, the Matthews coefficient suggests one molecule per asymmetric unit (Vm = 3.45 Å3 Da−1; 64% solvent). Three native data sets were collected to a resolution of 2.5 Å and merged to provide a set that is 94.7% complete, with an R sym value of 9.6%.
