ANNOUNCING PFAM RELEASE 3.3
Pfam is a collection of protein domain family alignments which were
constructed semi-automatically using profile hidden Markov models.
Pfam families contain functional annotation and cross-references to
other databases. Query sequences can be searched against the Pfam
library of profile hidden Markov models at the web sites below.
Pfam 3.3 contains 1390 families. 57% of proteins in SWISSPROT 35
and TrEMBL 5 have at least one match to a Pfam family.
The changes between Pfam release 3.3 and Pfam release 3.2 are:
46 new families have been added.
