ABSTRACT

The bioluminescence induced by luciferases of marine bacteria promotes repair of UV damaged DNA of Escherichia coli AB1886 uvrA6. It is shown that bacterial photolyase that implements photoreactivation activity is the major contributor to DNA repair. However, the intensity of bioluminescence increasing induced by UV-irradiation (SOS-induction) in bacterial cells is not enough for efficient photoreactivation.
