What's New in Release 23

Release 23 of Ensembl Bacteria has been loaded from EMBL-Bank release 119 into 62 multispecies Ensembl v76 databases. The current dataset contains 15,270 genomes (15,012 bacteria and 258 archaea) containing 52,562,716 protein coding genes loaded from 1,373,722 INSDC entries. This release includes 4,268 new genomes, 26 genomes with updated assemblies, 2,696 genomes with updated annotation, 245 genomes where the assigned name has changed, and 8 genomes removed since the last release.

Ensembl Bacteria

Over 10,000 genome sequences from bacteria and archaea have been annotated and deposited in the public archives of the members of the International Nucleotide Sequence Database Collaboration. This site provides access to complete, annotated genomes from bacteria and archaea (present in the European Nucleotide Archive) through the Ensembl graphical user interface (genome browser). More details about the integration are provided here

Programmatic access is available through the Ensembl Perl and REST-ful APIs and through publicly accessible mysql databases, along with full data dumps (including DNA sequence and protein sequence in FASTA format, annotations in GTF format, and mysql dump files). Due to the large number of these databases, there is some modification to the APIs, and database and FTP site structure, compared to that used for other branches of the taxonomy (e.g. the storage of many genomes in one database; the provision of lookup services to identify genomes by INSDC identifiers, taxonomy identifiers, or partial names. Full details are available here.

BioMart access is not available, but we are working on providing new, more powerful data mining tools to allow users to exploit these genomes. A selection of over 100 key bacterial genomes has been included in the pan-taxonomic Compara, and genes from all genomes are classified into families using HAMAP and PANTHER (more details)

Ensembl Bacteria has been developed with the support of the Microme project, a resource for bacterial metabolism.

Ensembl Genomes is developed by EMBL-EBI and is powered by the Ensembl software system for the analysis and visualisation of genomic data. For details of our funding please click here.
