                ANNOUNCING PFAM RELEASE 4.2

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 4.2 contains 1664 families.  61% of proteins in SWISSPROT 37
and TrEMBL 9 have at least one match to a Pfam family.
