Embl sequence tools

Wherever possible our databases and software are freely available to the scientific community, and we strongly encourage open access publication. Structural biology and imaging services enable life to be visualised across scales: from atomic snapshots of moving proteins to detailed videos of molecules within cells, tissues or organisms. The EMBL Imaging Centre, opening in the summer of , will encompass cutting-edge electron and light microscopy technologies.

EMBL supports researchers in performing functional omics analyses, to better understand the genome, transcriptome, proteome, and metabolome. Chemistry biology services at EMBL offer infrastructure and expertise to researchers interested in optimising biologically-relevant chemical compounds and gaining insights into protein function.

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. For sequence similarity searching, a variety of tools e. The main missions of the Service Programme of the EBI 1 centre on building, maintaining and providing biological databases and information services to support data deposition and exploitation. Main data sources are large-scale genome sequencing centres, individual scientists and the European Patent Office EPO.

The EMBL database is growing rapidly as a result of major genome sequencing efforts. Within a 12 month period the database size has increased from about 6. Submission of new sequence data and update information to the public database is an essential prerequisite for building and maintaining a complete and up-to-date data set allowing the scientific community to perform similarity searches and analysis on the latest nucleotide and protein sequence data.

This comprehensive repository of up-to-date primary sequences is essential for further computational analysis and genome research. Discovery of novel genes, identification of homologous genes, analysis of alternative splicing and detection of polymorphisms are only some of the uses of the database in the context of biomedical research, and this will only increase as large-scale sequencing efforts keep on depositing more high-throughput sequence data HTG and as more complete genomes are being added to the database.

Bioinformatics tools for database searching, sequence and homology searching, gene prediction, multiple sequence alignments, etc. Direct submissions from individual scientists or sequencing groups is an important source of new nucleotide sequences and descriptive biological information.

Often these submissions will include feature and function information based on experimental research, while genome project submissions typically include preliminary annotations based on prediction algorithms. Prior to submission, a World Wide Web-based interactive vector scanning service allows submitters to screen sequences for vector contamination.

Genome project submissions. Large-scale sequencing projects have become the major source of new sequence data. A direct dataflow to the EMBL Database from various international sequencing efforts exists to ensure immediate incorporation and distribution of new sequence data and descriptive information.

Particularly noteworthy is the collaboration on genome data acquisition with the genome projects in the Sanger Centre, one of the most productive sequencing centres in Europe and world-wide.

Database entries produced at the research sites are deposited and updated directly by the genome project groups using FTP or email. Through all stages, EBI biologists are communicating with the sequencing groups. New projects can be accommodated easily. Groups wishing to open accounts to submit genome sequence data should contact the database at datasubs ebi.

Updating existing database entries. Over time an entry which was correct when created may become out of date: authors may make corrections to the sequence itself, or may discover new features which require annotation. Since such findings are often not published, it is important that authors communicate their new findings to the database. Sequence alignment submissions. Unique alignment numbers e.

DS are assigned to each alignment submission and should be included in the published article. If you plan to use these services during a course please contact us.
