WebWhile in Turkey, Sancar had developed an interest in photoreactivation, the process by which DNA damaged by UV light is repaired by longer wavelength blue light. Rupert had identified photolyase, the enzyme that mediated the process by catalyzing the opening of the cyclobutane ring in pyrimidine dimers, and Sancar was eager to work him. WebDNA photolyases are light-activated enzymes that repair DNA damage induced by ultraviolet (UV) radiation. UV radiation causes two of the most abundant mutagenic and cytotoxic DNA lesions: cyclobutane pyrimidine dimers and 6-4 photolesions. Photolyases selectively bind to DNA and initiate the splitting of mutagenic pyrimidine dimers via photoinduced electron …
