Retrieve protein sequences that would exactly match to your query peptide

1. Select sequence data set:
    a) All UniProtKB plus isoform sequences
    b) Restricted by organism:
        Enter an organism from UniProt complete proteomes list
            

        Select organisms from UniProt reference proteomes list
          [A] [B] [C] [DE] [FG] [H] [IJKL] [M] [NO] [PQ] [R] [S] [T] [UVWXYZ]
2. Insert a peptide using single letter amino acid code (3 or more) below:
   Example: AAVEEGIVLGGGCALLR

3. Options:
   a)Limited to UniRef100 representative sequences within the UniProtKB
    Yes    No

   b)Treat Leucine (L) and Isoleucine (I) equivalent
    Yes    No
