Martin and Theo,

I think what Theo wanted is a computer program to scan for TF sites in
his DNA sequences. There are several methods and programs to do this.

1) get Gosh's Transcription Factor Database (TFD) from some where like or is it TFD. Use the GCG formated
  file with any of the GCG programs that find restriction sites.

2) get signal scan software from:

3) use Philipp Bucher's eukaryotic promoter database (EPD) with fasta

One you have some idea of what your promoter might have in it, couple
the piece of DNA to a reporter gene (luciferase is good) and begin
you reporter bashing. There are lots of reports showing the results of
this kind of exercise in the literature.
