Interaction of thymidylate synthetase with 5-nitro-2'-deoxyuridylate.

Abstract

5-Nitro-2'-deoxyuridylate (NO2dUMP) is a potent mechanism-based inhibitor of dTMP synthetase. After formation of a reversible enzymeìnhibitor complex, there is a rapid first order loss of enzyme activity which can be protected against by the nucleotide substrate dUMP. From studies of model chemical counterparts and the NO2dUMPdTMP synthetase complex, it has… (More)
