Characterization of Arabidopsis photolyase enzymes and analysis of their role in protection from ultraviolet-B radiation.


DNA photolyases are enzymes which mediate the light-dependent repair (photoreactivation) of UV-induced damage products in DNA by direct reversal of base damage rather than via excision repair pathways. Arabidopsis thaliana contains two photolyases specific for photoreactivation of either cyclobutane pyrimidine dimers (CPDs) or pyrimidine (6-4)pyrimidones (6… (More)
