2024年4月30日 · Non-redundant RefSeq protein records are currently provided for archaeal and bacterial RefSeq genomes, with the exception of selected reference genomes, by the NCBI prokaryotic genome annotation pipeline.

Select the sequence database to run searches against. No BLAST database contains all the sequences at NCBI. BLAST databases are organized by informational content (nr, RefSeq, etc.) or by sequencing technique (WGS, EST, etc.). more...

RefSeq: NCBI Reference Sequence Database A comprehensive, integrated, non-redundant, well-annotated set of reference sequences including genomic, transcript, and protein. Using RefSeq

2023年9月26日 · This example shows results from a search against the standalone ClusteredNR database (nr_clustered_seq) using the pig uricase protein (NP_999435) as a query. The count-clustermembers.sh script returns the number of sequences for the cluster represented by the Cavia porcellus uricase (XP_012998554.1).

2015年5月18日 · The Protein database is a collection of sequences from several sources, including translations from annotated coding regions in GenBank, RefSeq and TPA, as well as records from SwissProt, PIR, PRF, and PDB.

2022年5月2日 · Check out our new ClusteredNR database – derived from the default BLAST protein nr database by clustering sequences at 90% identity / 90% length (details below). Get quicker results and access to information about the distribution of your hits across a wider range of organisms and evolutionary distances.

2025年3月17日 · The Basic Local Alignment Search Tool (BLAST) finds regions of local similarity between sequences. The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches. BLAST can be used to infer functional and evolutionary relationships between sequences as well as help identify members …

We developed a fast method to construct local sub-databases from the NCBI-nr database for the quick similarity search and annotation of huge metagenomic datasets based on BLAST-MEGAN approach. A three-step sub-database annotation pipeline (SAP) was ...

2008年6月23日 · The best way to obtain BLAST databases is to download them from NCBI or cloud providers (currently from Google Cloud Platform and Amazon Web Services). These are the same databases available via the public BLAST Web Service (https://blast.ncbi.nlm.nih.gov), are updated regularly, and contain taxonomic information built into them.
