Light Shed On Photolyases, the repair of DNA Dimers

C&EN: Latest News - Light Shed On Photolyases: "DNA photolyase enzymes harness light energy to repair DNA damaged by ultraviolet radiation. The first X-ray structure of one of these enzymes bound to its damaged DNA substrate was recently reported by German crystallographers. In addition to confirming many suspicions about how these enzymes recognize and repair light-induced DNA damage, this long-awaited structure paints a picture of the enzyme midway through its work."
