Spore photoproduct lyase

Spore photoproduct lyase

Spore photoproduct lyase is an enzyme that repairs a particular kind of lesion that arises upon UV-radiation of bacterial DNA. This repair mechanism is one of the reasons for the resilience of certain bacterial spores. The enzyme is radical-SAM dependent. Through a series of radical reactions the photodimer, 3 5-thyminyl-5,6-dihydrothymine, is disconnected to give back two functional thymine rings. [cite journal | author = Susan C. Wang and Perry A.
