abstractText | Blue light governs a number of cellular responses in bacteria, plants, and animals, including photoreactivation, plant development, and circadian photoentrainment. These activities are mediated by a family of highly conserved flavoproteins, the photolyase/cryptochrome family. Photolyase binds to UV photoproducts in DNA and repairs them in a process called photoreactivation in which blue light is used to initiate a cyclic electron transfer to break bonds and restore the integrity of DNA. Cryptochrome, which has a high degree of sequence identity to photolyase, works as the main circadian photoreceptor and as a component of the molecular clock in animals, including mammals, and regulates growth and development in plants. |
