BLASTP search (protein versus protein) against single strain

Use this form to query an amino acid sequence against a database of protein sequences belonging to a single strain.

BLASTP searches take hundreds of times longer to run than BLASTN searches. This amounts to 10 or more minutes (per sequence) to search all protein sequences in this database.

If you would like to search broader taxonomic groups, including ALL proteins in this database, please consider using our DIAMOND BLASTP submission tool, which is significantly faster than BLASTP, yet very sensitive.
