Promoter Databases: How to search for binding-motifs??

[Stefan Kahlert]

Could someone please give me a recommendation:
 
I am looking for a promoter-database that can be searched for
binding-motifs over the net, or that can be integrated in DNASIS.
 
I only did fasta searches currently but the information that
the binding motif is repeatet in eg. an exon is of minor
interest for me:
 
I think I should better search on just the promoters.
But how to do so?
 
 
sincerely,
