title: The purification of orotidine-5'-phosphate decarboxylase from yeast by affinity chromatography.
abstract: We have prepared an affinity column for the purification of orotidine-5'-phosphate decarboxylase from yeast. The column effects a 3200-fold purification from yeast homogenate in one pass; simple additional steps produce enzyme that has been purified 6700-fold and is not contaminated by any other protein that can be detected by sodium dodecyl sulfate-acrylamide gel electrophoresis. Overall, 35% of the activity present in the yeast is recovered as pure enzyme. The resin for the column is synthesized by attaching the ethylenediamine amide of 5-(2-carboxyethyl)-6-azauridine 5'-phosphate to carboxymethyl-agarose.
