Abstract:
Ultraviolet (UV) light is one of the factors that causes baculovirus inactivation. However, little is known about the response of baculoviruses to UV light. In the present study, Bombyx mori nucleopolyhedrovirus (BmNPV) orf 65 (Bm65), the homolog of Autographa californica nucleopolyhedrovirus orf 79 (Ac79), a predicted endonuclease, was analyzed. Preliminary results indicated that Bm65 mainly accumulated within the nucleus and could improve the survival rate of Escherichia coli (E. coli) and BmNPV BVs after UV radiation, suggesting that Bm65 was involved in the repair of UV-induced DNA damage.

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
