- The products of umuD , umuC , and recA genes (SOS genes) are required for mutagenesis induced by radiation or chemical agents. Transcription of these SOS genes is repressed by a repressor, LexA protein in uninduced cells. Exposure of cells to DNA-damaging agents activates RecA protein to promote proteolytic cleavage of LexA protein. Inactivation of LexA protein by the cleavage consequently derepresses the SOS genes, umuD, C and recA . UmuD protein is then auto-cleaved, which is promoted by RecA protein ssDNA in a ATP-dependent manner. The processed UmuD protein is the active form for mutagenesis and the UmuD-UmuC complex functions as an error-prone translesion DNA polymerase.
