If by this you mean that you're looking for degenerate binding sites for a
family of transcription factors or other DNA binding proteins, you could
use Dan Prestridge's signalscan (which matches DNA sequence to the
transfac or transcription factor database):

To get the latest version, anon. ftp to biosci.cbs.umn.edu, to directory
pub/sigscan/pc or pub/sigscan/unix.  If you need installation instuctions
or help, send Email to danp at biosci.cbs.umn.edu.


 or the GCG program FINDPATTERNS which you can use to describe ambiguous
binding sites, or even Wu and Manber's 'agrep' (a variation on the unix
utility 'grep') which does very much the same thing (and is free):

ftp://ftp.cs.arizona.edu/agrep/agrep-2.04.tar.Z

"Wu and Manber, "Fast Text Searching with Errors", Technical report
#91-11, Department of Computer Science, University of Arizona, June 1991."

If not, I don't understand your question.

Cheers
Harry
