ATP-Linked Chimeric Nucleotide as a Specific Luminescence Reporter of Deoxyuridine Triphosphatase.

ABSTRACT: Nucleotide surveillance enzymes play important roles in human health, by monitoring damaged monomers in the nucleotide pool and deactivating them before they are incorporated into chromosomal DNA or disrupt nucleotide metabolism. In particular, deamination of cytosine, leading to uracil in DNA and in the nucleotide pool, can be deleterious, causing DNA damage. The enzyme deoxyuridine triphosphatase (dUTPase) is currently under study as a therapeutic and prognostic target for cancer. Measuring the activity of this enzyme is important both in basic research and in clinical applications involving this pathway, but current methods are nonselective, detecting pyrophosphate, which is produced by many enzymes. Here we describe the design and synthesis of a dUTPase enzyme-specific chimeric dinucle
