GenBank release 225: Over 1 billion sequence records stored!


GenBank release 225.0 (4/14/2018) has 208,452,303 traditional records (including non-bulk-oriented TSA) containing 260,189,141,631 base pairs of sequence data. In addition, there are 621,379,029 WGS records containing 2,784,740,996,536 base pairs of sequence data, 227,364,990 TSA records containing 205,232,396,043 base pairs of sequence data, and 14,782,654 TLS records containing 5,612,769,448 base pairs of sequence data.

During the 60 days between the close dates for GenBank releases 224.0 and 225.0, the traditional portion of GenBank grew by 6,558,433,533 base pairs and by 1,411,748 sequence records. During that same period, 86,960 records were updated – an average of 24,978 records added or updated per day.

The NCBI BioCollections database links specimen vouchers and sequence records to home institutions


A paper in the January 2018 issue of Database describes the NCBI BioCollections database, a curated dataset of metadata for culture collections, museums, herbaria and other natural history collections connected to sequence records in GenBank. The BioCollections database was established to allow the association of specimen vouchers and related sequence records to their home institutions. This process also allows back-linking from the home institution for quick identification of all records originating from each collection.

The rapidly growing set of GenBank submissions frequently includes records that are derived from specimen vouchers.  Correct identification of the specimens studied, along with a method to associate the sample with its institution, is critical to the outcome of related studies and analyses.

New repository records are added to the database if they are submitted to the International Nucleotide Sequence Database Collaboration (INSDC) along with sequence data. Each record now provides information about the institution that houses the collection, standard Institution Code, mailing address, and associated webpage if available.

The BioCollections database is maintained and curated by the Taxonomy group at NCBI.

Identical Protein Groups: Non-redundant access to protein records


Have you ever searched the NCBI Protein database and been overwhelmed with the number of sequences returned? Have you tried searching with a protein name, thinking that would greatly limit the results, only to still be presented with many sequences (all with the same name)? It’s a common problem in this time of greatly expanding sequence databases powered by large-scale genomic sequencing of similar organisms. Redundancy in the sequence databases is high and only getting worse.

To address this, in 2013 NCBI released the WP records, which collect identical protein sequences annotated on bacterial genomes. In 2014, NCBI released the Identical Protein Reports on Protein records, which displays information about all other proteins identical to that protein. Now, we are releasing a new resource: Identical Protein Groups (IPG).  IPG offers several features:
