Oxidative damage to a cell’s DNA is constant and destructive and a complex suite of enzymes have evolved to repair and maintain it. In an important new step in teasing out these complex processes, an enzyme component known as Zf-GRF, which is highly conserved in several enzymes and across species, has been shown to be a key molecular tools that binds and orients repair enzymes to DNA.
