The major damage induced in DNA by ultraviolet light is the induction of cyclobutane pyrimidine dimers (CPDs). Amsacta moorei entomopoxvirus (AMEV) encodes a CPD photolyase (AMV025) with a putative role in converting these dimers back into monomers. In infected Lymantria dispar cells transcription of the AMV025 gene started 8 h post inoculation (p.i.) and continued through 38 h p.i. Transcription was inhibited by a DNA synthesis blocker. Transient expression in an Escherichia coli strain that lacks its endogenous photolyase, rescued growth of the UV-irradiated bacteria in a light-dependent manner, showing that AMV025 encodes a functional DNA photolyase.
