Release 2 of TREMBL: a protein sequence database supplementing the SWISS-PROT Protein Sequence Data Bank

Introduction

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.

Release 2.0 of TREMBL

This TREMBL release is created from the EMBL Nucleotide Sequence Database release 49 and contains 116'379 sequence entries, comprising 31'293'053 amino acids.

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

SP-TREMBL (SWISS-PROT TREMBL) contains the entries (96'757) 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 12 subsections:

REM-TREMBL (REMaining TREMBL) contains the entries (19'622) that we do not want to include in SWISS-PROT.

Weekly updates of TREMBL

Weekly cumulative updates of TREMBL will be available by anonymous FTP and from the EBI SRS server from the beginning of March 1997 onwards.

Access/Data distribution

TREMBL is available through the FTP or SRS at EBI, and on the SWISS-PROT CD-ROM. SP-TREMBL is searchable on the FASTA server of the EBI and will be soon searchable on the BLITZ server of the EBI.

TREMBL has been prepared by:

Rolf Apweiler, Sergio Contrino, Vivien Junker, Stephanie Kappus, Fiona Lang, Michele Magrane, Maria Jesus Martin, Nicoletta Mitaritonna and Claire O'Donovan at the EMBL Outstation - European Bioinformatics Institute (EBI) in Hinxton, UK;
Amos Bairoch and Alain Gateau at the Medical Biochemistry Department of the University of Geneva, Switzerland.
