The MimoBlast tool is designed to check if there are peptides in the BDB database that are identical or similar to the peptides user submitted. Highly similar peptides obtained with various targets might also be TUPs. Besides, peptides similar to a known TUP may also be TUPs. For example, SVSVGMNPSPRP is very likely to be a TUP because it is nearly identical to SVSVGMKPSPRP, a notorious TUP. If you got the former peptide, a BLAST against the BDB database would remind you it may be a TUP. Here we go! (Download standalone tools: Windows | Ubuntu);
