Peptide search
The peptide search tool allows you to submit peptide sequences of at least 7 residues and to find all UniProtKB sequences which have an exact match to the query sequence.
To access the tool, click on the ‘Peptide search’ link in the header which is at the top of every page on the UniProt website: https://www.uniprot.org/peptide-search
All you need to provide as input is a peptide sequence at least three amino acids long. You have the option to choose a taxonomy restriction and you can also specify whether you would like the tool to treat isoleucine and leucine as equivalent (figure 48).
