Choose the appropriate BLAST program and database:

blastp - query against the UniProt Knowledgebase (Swiss-Prot + TrEMBL)

Taxonomic groups (not available for PDB and translated EST):

select a database subsection

To restrict the search to a particular taxon, it is much faster to select a database subsection from the drop-down list on the left than to specify your own taxonomic group in the box below. This also gives more accurate statistics.

or specify a taxonomic group

Enter a species name, a TaxID or the latin name of a taxonomic group (elements of the OC, OS and OX lines) to restrict your search to a particular taxon. You may enter a list separated by semicolons (";"). Example: Fungi; Homo sapiens.

or select a microbial proteome

Non-redundant Swiss-Prot+TrEMBL complete proteome sets, see the HAMAP pages.

Search only Swiss-Prot (curated sequences) Exclude fragment sequences

blastp - query against another protein database Please, supply an email address if you select the translated ESTs.

tblastn - query against the six-frame translation of a nucleotide database

Taxonomic groups:

or select a microbial genome

EMBL genome records, including plasmids.

Your email address: If an e-mail address is provided, results will be automatically mailed back (recommended for tblastn searches).

Options:

Comparison Matrix:
Number of best scoring sequences to show:
Number of best alignments to show:

Setting the E threshold: (Number of expected matches in a random database)

Filter the sequence for low-complexity regions

Gapped alignment

Identity BLAST

For a more 'advanced' BLAST2 search (with more options and programs, and a larger variety of databases) please use the original submission form at EMBnet-CH (Lausanne).
