Structural basis for DNA 3′-end processing by human tyrosyl-DNA phosphodiesterase 1

Abstract

Human tyrosyl-DNA phosphodiesterase 1 (Tdp1) repairs covalently trapped topoisomerase 1B-DNA complexes and other lesions, and is a target for anticancer drug development. Here the authors use an integrated structural approach to shed light onto the molecular basis of DNA end-processing by Tdp1.
