TrEMBL is a protein sequence database supplementing the SWISS-PROT
Protein Sequence Data Bank. TrEMBL contains the translations of all
coding sequences (CDS) present in the EMBL Nucleotide Sequence
Database not yet integrated in SWISS-PROT. TrEMBL can be considered
as a preliminary section of SWISS-PROT. For all TrEMBL entries
which should finally be upgraded to the standard SWISS-PROT
quality, SWISS-PROT accession numbers have been assigned.


The goal of this TrEMBL release is to achieve synchronization with
SWISS-PROT release 39.0. Therefore, all sequence entries present in
SWISS-PROT release 39.0 have been removed from TrEMBL release 13,
further upgrading of existing TrEMBL entries was achieved and only
a very few new entries were incorporated.

TrEMBL release 14 contains 351'834 sequence entries, comprising
100'069'442 amino acids.

TrEMBL is split in two main sections: SP-TrEMBL and REM-TrEMBL.

SP-TrEMBL (SWISS-PROT TrEMBL) contains the entries (297'973) 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):             11776 entries
fun.dat (Fungi):                8877 entries
hum.dat (Human):               13757 entries
inv.dat (Invertebrates):       44786 entries
mam.dat (Other Mammals):        4977 entries
mhc.dat (MHC proteins):         5264 entries
org.dat (Organelles):          25730 entries
phg.dat (Bacteriophages):       2666 entries
pln.dat (Plants):              28878 entries
pro.dat (Prokaryotes):         62006 entries
rod.dat (Rodents):             10226 entries
unc.dat (Unclassified):           31 entries
vrl.dat (Viruses):             72237 entries
vrt.dat (Other Vertebrates):    6762 entries

REM-TrEMBL (REMaining TrEMBL) contains the entries (53'861)
that we do not want to include in SWISS-PROT.
