(17) After introduction of these fusions into the chromosomal DNA of mutants affected in sacB regulation, it was possible to reveal different targets for the regulatory genes sacU, sacQ and sacS: the sacU and sacQ genes act on a region located near or just upstream from the promoter, and the sacS gene, which is involved in the induction process, acts on the palindromic structure.
(18) This regulatory sequence is about 50 base-pairs long and is centered 125 base-pairs upstream from the transcription start site in a region containing a 16 base-pair palindromic structure.
