identifying TF seq.'s in a promoter

Dear Ron,

Do you have access to a Macintosh running MacVector? If so, TFD
(Transcription Factor Database), which I'm sure you know about (I download
my files via the Hopkins BioGopher) actually has the complete list of
consensus sequences in MacVector format (I'm sure there are other formats,
although I wouldn't know how to use them). I downloaded the TF database
file, took a promoter sequence directly off GenBank, walked the disk over
to the lab next door running MacVector, performed a subsequence search
(you can specify # of allowable mismatches) and in several minutes got a
47-page single-spaced printout of potential consensus sequences (the
subsequence file originally supplied with MacVector only came up with 8
pages). Pretty amazing.
