Escherichia coli dihydropyrimidine dehydrogenase (EcDPD) catalyzes the NADH-dependent reduction of uracil and thymine to the corresponding 5,6-dihydropyrimidines to control their metabolite pools. EcDPD consists of two subunits, PreT and PreA, and requires FAD, FMN, and Fe-S clusters for activity. Recombinant EcDPD with a C-terminal His6-tagged-PreA subunit was overproduced in a DPD-lacking E. coli cells with augmented Fe-S cluster synthesis. Anaerobic purification resulted in purified enzyme with a specific activity of 13 μmol min-
