Transcription unit          
Name: uvrB
Gene(s): uvrB   Genome Browser M3D Gene expression COLOMBOS
Note(s): The full activity of the uvrB promoter region requires three promoters (uvrBp1, uvrBp2, and uvrBp3) and is repressed by both the DnaA and LexA proteins |CITS:[29967594]|. In the absence of the SOS response, both DnaA and LexA repress transcription of the uvrB gene and function independently of each other, but in an additive manner |CITS:[29967594]|.
Evidence: [BTEI] Boundaries of transcription experimentally identified
[LTED] Length of transcript experimentally determined

                          -35                    -10        +1                   
Note(s): Transcription of uvrBp3 is indirectly inhibited by LexA. This transcript terminates within or near the LexA-binding site, which regulates uvrBp2, and it is possible that termination does not occur in vivo Sancar GB,1982

Note(s): 2DnaA and LexA compete for binding to and regulation of the uvrBp3 promoter, as DnaA-box6 overlaps with LexA-box4. The transcription control of uvrBp3 largely depends on DnaA-box6 during the SOS response Wurihan,2018
