Prosite: a dictionary of sites and patterns in proteins

Background PROSITE is a compilation of sites and patterns found in protein sequences. The use of protein sequence patterns (or motifs) to determine the function of proteins is becoming very rapidly one of the essential tools of sequence analysis. This reality has been recognized by many authors 1,2. While there have been a number of recent reports It is for these reasons that we have developed, since 1988, a dictionary of sites and patterns which we call PROSITE.
