photolyase
(= DNA photolyase)
Family of ubiqitous enzymes found in bacteria, archaebacteria and eukaryotes that can repair UV-induced DNA damage. The protein (between 454 to 614 residues) is associated with two prosthetic groups, FADH and a light-harvesting cofactor, MTHF (5,10-methenyltetrahydofolyl polyglutamate). Light is needed for the repair step.
