INTRODUCTION
============
TrEMBL is a computer-annotated protein sequence database
complementing the Swiss-Prot Protein Knowledgebase.
TrEMBL contains the translations of all coding sequences
(CDS) present in the EMBL/GenBank/DDBJ Nucleotide Sequence
Databases and also protein sequences extracted from the
literature or submitted to Swiss-Prot, which are not yet
integrated into Swiss-Prot. For all TrEMBL entries
which should finally be upgraded to the standard
Swiss-Prot quality, Swiss-Prot accession numbers have
been assigned.
RELEASE 23.0 OF TrEMBL
=====================
This TrEMBL release has been produced in synch with
Swiss-Prot release 41. It was created from the EMBL
Nucleotide Sequence Database release 73 and contains
921'952 entries and 40'914'860 amino acids.
TrEMBL is split in two main sections:
SP-TrEMBL and REM-TrEMBL:
SP-TrEMBL (Swiss-Prot TrEMBL) contains the entries
(830'525) which should be eventually incorporated into
Swiss-Prot. Swiss-Prot accession numbers have been
assigned for all SP-TrEMBL entries.
SP-TrEMBL is organized in subsections:
arc.dat (Archaea): 1736 entries
arp.dat (Complete Archaeal proteomes): 31625 entries
fun.dat (Fungi): 15977 entries
hum.dat (Human): 34880 entries
inv.dat (Invertebrates): 79680 entries
mam.dat (Other Mammals): 12223 entries
mhc.dat (MHC proteins): 8813 entries
org.dat (Organelles): 73538 entries
phg.dat (Bacteriophages): 6448 entries
pln.dat (Plants): 80929 entries
pro.dat (Prokaryotes): 79736 entries
prp.dat (Complete Prokaryotic Proteomes): 181432 entries
rod.dat (Rodents): 40143 entries
unc.dat (Unclassified): 331 entries
vrl.dat (Viruses): 82490 entries
vrt.dat (Other Vertebrates): 14889 entries
vrv.dat (Retroviruses): 85655 entries
107'123 new entries have been integrated in SP-TrEMBL.
The sequences of 1713 SP-TrEMBL entries have been updated
and the annotation has been updated in 252'549 entries.
In the document deleteac.txt, you will find a list of all
accession numbers which were previously present in TrEMBL,
but which have now been deleted from the database.
REM-TrEMBL (REMaining TrEMBL) contains the entries (91'427)
that we do not want to include in Swiss-Prot.
ACCESS/DATA DISTRIBUTION
========================
FTP server: ftp.ebi.ac.uk/pub/databases/trembl
SRS server: http://srs.ebi.ac.uk/
TrEMBL is also available on the SWISS-PROT CD-ROM.
SWISS-PROT + TrEMBL is searchable on the following
servers at the EBI:
FASTA3 (http://www.ebi.ac.uk/fasta33/)
BLAST2 (http://www.ebi.ac.uk/blast2/)
Scanps (http://www.ebi.ac.uk/scanps/)
MPSrch (http://www.ebi.ac.uk/MPsrch/)
For each TrEMBL release, a synchronized version of
the concurrent SWISS-PROT release is distributed at
ftp.ebi.ac.uk/pub/databases/trembl/swissprot/
We also produce every week a complete non-redundant
protein sequence collection by providing three
compressed files (these are in the directory
/pub/databases/sp_tr_nrdb on the EBI FTP server:
sprot.dat.gz, trembl.dat.gz and trembl_new.dat.gz.)
TrEMBL and Swiss-Prot in XML format
===================================
A release version of TrEMBL and Swiss-Prot in XML format
is provided with this release of TrEMBL. More information
is available at
http://www.ebi.ac.uk/swissprot/SP-ML
and the data can be downloaded from
ftp://ftp.ebi.ac.uk/pub/databases/trembl/xmlftp://ftp.ebi.ac.uk/pub/databases/sp_tr_nrdb/xml
