The Beta release of TREMBL, a protein sequence database supplementing the 
SWISS-PROT Protein Sequence Data Bank is now available from  
ftp.ebi.ac.uk in directory /pub/databases/trembl.


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 
integrated in SWISS-PROT. At the moment we treat TREMBL as an independent 
dataset in SWISS-PROT format, but shortly TREMBL will become a part of 


This TREMBL release is created from the EMBL nucleotide sequence release 46
and contains 98'447 sequence entries, comprising 25'879'831 amino acids.

TREMBL is split in two main sections; SP-TREMBL and REM-TREMBL:

SP-TREMBL (SWISS-PROT TREMBL) contains the entries (81'861) which should be 
incorporated into SWISS-PROT. SP-TREMBL is partially redundant against 
SWISS-PROT, since approximately 40'000 SP-TREMBL entries are only 
additional sequence reports of proteins already in SWISS-PROT. We will try 
to merge these sequence reports as fast as possible with the already 
existing SWISS-PROT entries for these proteins, so as to make SWISS-PROT
and TREMBL completely nonredundant.
SP-TREMBL is organized in subsections:

fun.dat (Fungi):                3772 entries
inv.dat (Invertebrates):        9689 entries
mam.dat (Other Mammals):        1907 entries
mhc.dat (MHC proteins):         2007 entries
org.dat (Organelles):           5241 entries
phg.dat (Bacteriophages):        939 entries
Pln.dat (Plants):               5294 entries
pri.dat (Primates):             6425 entries
pro.dat (Prokaryotes):         15645 entries
rod.dat (Rodents):              5837 entries
unc.dat (Unclassified):          201 entries
vrl.dat (Viruses):             22677 entries
vrt.dat (Other Vertebrates):    2227 entries

REM-TREMBL (REMaining TREMBL) contains the entries (16'586) that we do 
not want to include in SWISS-PROT.

TREMBL is also available on the SWISS-PROT CD-ROM.
