Accordingly protein sequence profiles derived from multiple sequence alignments provide an alternative description of functional motifs characterizing families of related sequences. Such profiles conveniently reflect functional necessities by pointing out proximity at conserved sequence positions as well as depicting distances at variable positions. Discovering significant conservation characteristics within the variable positions of profiles mirrors group-specific and, in particular, evolutionary features of the underlying sequences.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>We describe the tool <jats:bold><jats:italic>PRO<\/jats:italic><\/jats:bold><jats:italic>file analysis based on<\/jats:italic><jats:bold><jats:italic>M<\/jats:italic><\/jats:bold><jats:italic>utual<\/jats:italic><jats:bold><jats:italic>I<\/jats:italic><\/jats:bold><jats:italic>nformation<\/jats:italic> (PROMI) that enables comparative analysis of user-classified protein sequences.
