title: Polymer-linked 6-azauridine 5'-monophosphate, a resin of high bioaffinity to orotidine-5'-phosphate decarboxylase.
abstract: Condensation of 6-azauridine with ethyl levulinate, followed by saponification or phosphorylation, leads to 2',3'-O-[1-(2-carboxyethyl)ethylidene]-6-azauridine and its 5'-monophosphate. The latter was coupled to 6-aminohexylagarose via its carboxylic group. Using the same synthetic route, agarose-linked uridine 5'-monophosphate has been prepared. Both polymers show specific binding toward orotidine-5'-monophosphate decarboxylase. The immobilized inhibitor (6-azauridine 5'-monophosphat) binds the enzyme more strongly than the immobilized uridine 5'-monophosphate. Both resins have been used to separate orotidine-5'-monophosphate decarboxylase from orotidine-5'-monophosphate pyrophosphorylase.
