There are lots of such tools, both to search known databases or to search for
The following link shows lots of such ones.
If you're going to search genomic sized chunks, a program I wrote called 'tacg'
is pretty good and searches for IUPAC patterns (with or without errors), regular
expressions, matrix descriptions, as well as for windows satisfying rules for
((pattern A AND pattern B) NOT (Pattern C AND pattern D)) XOR (Pattern E NOT
PAttern F)) in a sliding window of 1500 bases.
Described in more detail at:
Lemme know if you want the latest version. Runs on linux, MacOSX, Solaris,
probably other *nixs

However, in addition I am interested in control sequences in DNA and wonder if there are any tools (within R or another (similar?) environment) that would allow one to search large chunks of sequence for enrichment for any known cis-acting control elements (promoters, enhancers, silencers, repeat elements, MAR's, etc.)?
