SWISS-PROT is a curated protein sequence database which strives to provide
a high level of annotation (such as the description of the function of a pr
otein, its domain structure, post-translational modifications, variants, et
c.), a minimal level of redundancy and high level of integration with other
databases. Recent developments of the database include: cross-references t
o additional databases; a variety of new documentation files and improvemen
ts to TrEMBL, a computer annotated supplement to SWISS-PROT. TrEMBL consist
s of entries in SWISS-PROT-like format derived from the translation of all
coding sequences (CDS) in the EMBL nucleotide sequence database, except the
CDS already included in SWISS-PROT. The URLs for SWISS-PROT on the WWW are
