Abstract

We report herein a simple and convenient luminescent assay for detection of base excision repair enzyme activity using an Ir(III) complex as a G-quadruplex selective probe. Using uracil-DNA glycosylase (UDG) as a model enzyme, the assay achieved high sensitivity and selectivity for UDG over other tested enzymes. The utility of the assay for screening potential UDG inhibitors was also demonstrated.
