Table 3a. Examples of input and output from the Analyse Substrates service. a) A table showing data for submission to the Analyse Substrates service. The user is asked to supply a plain text file with elements separated by tabs. There should be one cleavage per line, and each cleavage should consist of the MEROPS identifier of the peptidase performing the cleavage, the UniProt accession of the protein substrate, and the residue number after which cleavage occurs (the P1 residue). Residue numbering should be taken from the relevant UniProt entry. Column headings (shown here for guidance only) are not required.
