Photoreactivation is the repair of DNA damage induced by ultraviolet light radiation using the energy contained in visible-light photons. The process is carried out by a single enzyme, photolyase, which is part of a large and ancient photolyase/cryptochrome gene family. We have characterised a photolyase gene from the microsporidian parasite, Antonospora locustae (formerly Nosema locustae) and show that it encodes a functional photoreactivating enzyme and is expressed in the infectious spore…
