DIAMOND BLASTP search (protein versus protein) against one or more strains

Use this form for fast querying of a protein sequence against a broader taxonomic group and millions of proteins.

The DIAMOND BLASTP command can be used as a fast and sensitive alternative to BLASTP searches. Using an amino acid query sequence, it can search a database of proteins sequences hundreds of times faster than BLASTP.

More details on DIAMOND are available at the developers' website or in the following publication:

On this site, you can use DIAMOND BLASTP to query an amino acid sequence against a protein sequence database. For searches of large data sets (e.g. protein sequences from ALL strains in this database), this is now the only available option.

Note 2: If you prefer to use BLASTP, you can perform a BLASTP search against a single isolate here.

Start typing and select from one of the taxonomic groups

OR start typing and select a single strain

Specify custom alignment options (optional)

Include all genomes Only include complete genomes

Paste your amino acid sequence in FASTA format
