2. Introduction PROSITE is a method of determining what is the function of uncharacterized proteins translated from genomic or cDNA sequences. It consists of a database of biologically significant sites and patterns formulated in such a way that with appropriate computational tools it can rapidly and reliably identify which known family of protein (if any) the new sequence belongs to.

3. Continued... In some cases the sequence of an unknown protein is too distantly related to any protein of known structure to detect its resemblance by overall sequence alignment, but it can be identified by the occurrence in its sequence of a particular cluster of residue types which is variously known as a pattern, motif, signature, or fingerprint.  Currently, most of the new PROSITE entries are centered around profiles and are developed by the PROSITE collaborators at the  SIB Swiss Institute of Bioinformatics  in Geneva and Lausanne.

4. Database convention General structure : The PROSITE database is composed of two ASCII (text) files. The first file (PROSITE.DAT) is a computer readable file that contains all the information necessary to programs that will scan sequence(s) with patterns and/or matrices. The second file (PROSITE.DOC) contains textual information that fully documents each pattern and profile
