(Figure Presented) Before and after: Crystal structures of the DNA (6-4) photolyase from D. melanogaster-one structure in complex with DNA containing a (6-4) lesion (see picture) and one in which the lesion has been repaired-provide new insight into lesion recognition and repair. The proposed mechanism for light-induced, electron-transfer-based repair of the (6-4) lesion does not proceed via an oxetane intermediate.
