General Information

General Information Comment Organism
physiological function photolyase may function to facilitate DNA repair during UVB exposure. Increased resistance of Photobacterium angustum as compared to Sphingopyxis alaskensis under high UVB doses results from a UVB-induction of CPD photolyase(s) that may directly repair DNA damage and/or act indirectly by enhancing the rate of nucleotide excision repair. Presence of 3 genes coding for DNA photolyase type I enzymes in Photobacterium angustum compared to only 1 for Sphingopyxis alaskensis. Photoresistance strategy may involve a capacity to utilize 3 distinct gene products, including the UVB-induced overexpression of the gene(s). Photolyase activity not only leads to the repair of DNA through a photochemical process, but may also enhance the efficiency of nucleotide excision repair, which is far more efficient in Photobacterium angustum than in Sphingopyxis alaskensis Photobacterium angustum S14
