Photolyases (EC 4.1.99.3) are DNA repair enzymes that repair damage caused by exposure to ultraviolet light. These enzymes require visible light (from the violet/blue end of the spectrum) both for their own activation[1] and for the actual DNA repair.[2] The DNA repair mechanism involving photolyases is called photoreactivation. They mainly convert pyrimidine dimers into a normal pair of pyrimidine bases. Photo reactivation, the first DNA repair mechanism to be discovered, was described initially by Albert Kelner in 1949[3] and independently by Renato Dulbecco also in 1949.[4][5][6]
