Exact promoter of the blue light receptor

This is a promoter which normally lies before the ycgZ gene, a part of an operon consisting of several genes used by E.coli for regulating the structure of their biofilm. It is regualted by the ycgF/E system. This ssytem has a receptor, ycgF, which is responsive of blue light. when blue light strikes, the receptor changes conformation and dimerizes. This allows it to bind to the ycgE repressor through its EAL-domain releasing the repressor from the promoter region. the inverted repeats shown here is the DNA we expect ycgE to bind to when repressing the promoter.
