Prosite is a database of regular expressions that match potentially diagnostic regions for structural/functional classification of proteins. EMBOSS needs this database for the patmatmotifs program.
PROSITE can be obtained via anonymous FTP.3.12
You may need to create a PROSITE subdirectory under data in the EMBOSS installation directory.
Then run prosextract to build the EMBOSS Prosite database.
% prosextract Builds the PROSITE motif database for patmatmotifs to search Enter name of prosite directory: /data/prosite
PROSITE is now integrated into your EMBOSS installation.
