The program Pratt was written to discover such conserved
It was primarily designed for working with protein sequences, but can
also be used for analysing DNA sequences. Pratt takes as input a set of
unaligned sequences (in a single file - FastA or Swiss-Prot format), and
will discover patterns matching some minimum number of these sequences
(the user sets this minimum number). Pratt can discover PROSTIE-like
patterns including flexible gaps and ambiguous pattern positions.
See http://www.ii.uib.no/~inge/Pratt.html for more info, source
code (ANSI C) for Pratt can be downloaded from ftp.ii.uib.no
(directory /pub/bio/Pratt) or from ftp.ebi.ac.uk.

A new version of Pratt will soon be announced.
