The EMBL Nucleotide Sequence Database: major new developments.

The EMBL Nucleotide Sequence Database (http://www.ebi.ac.uk/embl/) incorporates, organizes and distributes nucleotide sequences from all available public sources. The database is located and maintained at the European Bioinformatics Institute (EBI) near Cambridge, UK. In an international collaboration with DDBJ (Japan) and GenBank (USA), data are exchanged amongst the collaborating databases on a daily basis to achieve optimal synchronization. Webin is the preferred web-based submission system for individual submitters, while automatic procedures allow incorporation of sequence data from large-scale genome sequencing centres and from the European Patent Office (EPO). Database releases are produced quarterly. Network services allow free access to the most up-to-date data collection via FTP, Email and World Wide Web interfaces. EBI's Sequence Retrieval System (SRS) integrates and links the main nucleotide and protein databases plus many other specialized molecular biology databases. For sequence similarity searching, a variety of tools (e.g. Fasta, BLAST) are available which allow external users to compare their own sequences against the latest data in the EMBL Nucleotide Sequence Database and SWISS-PROT. All resources can be accessed via the EBI home page at http://www.ebi.ac.uk.

The InterPro Database, 2003 brings increased coverage and new features.

InterPro, an integrated documentation resource of protein families, domains and functional sites, was created in 1999 as a means of amalgamating the major protein signature databases into one comprehensive resource. PROSITE, Pfam, PRINTS, ProDom, SMART and TIGRFAMs have been manually integrated and curated and are available in InterPro for text- and sequence-based searching. The results are provided in a single format that rationalises the results that would be obtained by searching the member databases individually. The latest release of InterPro contains 5629 entries describing 4280 families, 1239 domains, 95 repeats and 15 post-translational modifications. Currently, the combined signatures in InterPro cover more than 74% of all proteins in SWISS-PROT and TrEMBL, an increase of nearly 15% since the inception of InterPro. New features of the database include improved searching capabilities and enhanced graphical user interfaces for visualisation of the data. The database is available via a webserver (http://www.ebi.ac.uk/interpro) and anonymous FTP (ftp://ftp.ebi.ac.uk/pub/databases/interpro).

Low back pain, sacroiliitis, and the relationship with HLA-B27 in Crohn's disease.

OBJECTIVE: To determine the prevalence of sacroiliitis in patients who have back pain in Crohn's disease (CD) using computed tomography (CT); and to reassess the association of sacroiliitis in CD with HLA-B27. METHODS: A total of 134 consecutive patients with CD completed a questionnaire about musculoskeletal symptoms. Those reporting low back pain were assessed, including plain radiographs and CT of the sacroiliac joints. HLA-B27 status was determined in patients with and without back pain. RESULTS: There were 70 (52%) patients with low back pain, of whom 31 (45%) had CT evidence of sacroiliitis. These were characterized by more frequent morning spinal stiffness and positive sacroiliac compression tests even when sacroiliitis was not suspected. Nine had previously recognized radiological and clinical ankylosing spondylitis (AS), and of these 78% were HLA-B27 positive. Of those with newly identified sacroiliitis, 14% were HLA-B27 positive. This frequency was not statistically dissimilar to the 9% HLA-B27 positivity of those without back pain. CONCLUSION: Sacroiliitis defined by CT is a common cause of low back pain in CD. A relationship of sacroiliitis and HLA-B27 could be confirmed only for those with classical AS. Our results accord with the possibility that sacroiliitis in CD is an isolated phenomenon, which is unrelated to HLA-B27 and which may evolve into classical spinal ankylosis in genetically susceptible subjects.

The EMBL Nucleotide Sequence Database.

The EMBL Nucleotide Sequence Database (aka EMBL-Bank; http://www.ebi.ac.uk/embl/) incorporates, organises and distributes nucleotide sequences from all available public sources. EMBL-Bank is located and maintained at the European Bioinformatics Institute (EBI) near Cambridge, UK. In an international collaboration with DDBJ (Japan) and GenBank (USA), data are exchanged amongst the collaborating databases on a daily basis. Major contributors to the EMBL database are individual scientists and genome project groups. Webin is the preferred web-based submission system for individual submitters, whilst automatic procedures allow incorporation of sequence data from large-scale genome sequencing centres and from the European Patent Office (EPO). Database releases are produced quarterly. Network services allow free access to the most up-to-date data collection via FTP, email and World Wide Web interfaces. EBI's Sequence Retrieval System (SRS), a network browser for databanks in molecular biology, integrates and links the main nucleotide and protein databases plus many other specialized databases. For sequence similarity searching, a variety of tools (e.g. Blitz, Fasta, BLAST) are available which allow external users to compare their own sequences against the latest data in the EMBL Nucleotide Sequence Database and SWISS-PROT. All resources can be accessed via the EBI home page at http://www.ebi.ac.uk.
