Protein accession numbers / IDs must be in the same format as was used in the FASTA file with protein sequences (database). \ The only exception to this rule is that accession numbers / IDs may be optionally suffixed with the peptide\'s position in its protein between brackets. \ For example: CLH1_HUMAN[1612-1620] will be matched to CLH1_HUMAN in a FASTA file with protein sequences. \ Amino acids in the petide sequences must be in uppercase. =============================================== *Protein sequences* =============================================== Input file containing all protein sequences in FASTA format. \ This tool will look for any type of protein ID in the first part of FASTA sequence headers up until the first white space. \ Optionally multiple IDs may be present separated with pipe symbols (|) or semicolons (;). \ Optionally IDs may be prefixed with a database namespace and a colon (:). \ For example the accession number P32234 as well as the ID 128UP_DROME would be recognized in both this sequence header: >UniProtAcc:P32234|UniProtID:128UP_DROME GTP-binding protein 128up - Drosophila melanogaster (Fruit fly) and in this one: >P32234|128UP_DROME GTP-binding protein 128up - Drosophila melanogaster (Fruit fly) =================================================== *N-terminal and C-terminal sequence context length* =================================================== Integers specifying the length of the N-terminal and C-terminal sequence context to retrieve starting from the modification site. \ Note that the width of a miscleavage site is 0 amino acids. \ When defaults are used for both the N-terminal and C-terminal sequence context lengths, \ the total sequence context length for a miscleavage site will be: (N-terminal sequence context) + (C-terminal sequence context) = 5 + 5 = 10. =============================================== *Cleavage amino acid and terminus* =============================================== This tool assumes the peptides were derived from cutting with a proteolytic enzyme, \ that should have cut on the *cleavage terminal* side of all *cleavage amino acids*. \ =============================================== *Padding character* =============================================== Optional padding character to fill N-terminal or C-terminal positions in the sequence context, \ when the protein was too short to get a complete sequence context. \ Defaults to - a.k.a. dash or alignment gap character. \ ----- **Getting input data** .. _my folder utility: http://mascotinternal.chem.uu.nl/mascot/cgi/uu_myfolder.pl This tool requires \ peptide sequences in TAB delimited format and \ protein sequences from which the peptides were derived in FASTA format. \ If your peptide sequences are not in TAB delimited format, you can convert from: - FASTA format using *FASTA manipulation* -> *FASTA-to-Tabular* - A format using a different delimiter using *Text Manipulation* -> *Convert* When your peptides were derived from a mass spectrometry experiment and identified with a search engine like Mascot, Sequest, etc.,\ please make sure you provide the same FASTA database for this tool as the one used for your search. If you used Mascot hosted by the Biomolecular Mass Spectrometry and Proteomics Group @ Utrecht University, \ you can use the `my folder utility`_ to download the FASTA databases from the Mascot server. ----- **Examples** Example input for peptides identified with a Mascot search, \ some with phosphorylated residues indicated by pS, pT or pY \ and in TAB delimited format:: sequence score peptide mr mass delta (abs) mass delta (ppm) all protein matches AGNAARDN 54.24 787.357254 -4.223E-5 -0.05334300253998803 H2A1B_HUMAN[67-74]; H2A1C_HUMAN[67-74]; H2A1D_HUMAN[67-74] KLpSAAVVLI 11.48 912.600784 0.001608 1.7619971713721432 OSGI2_HUMAN[405-413] RAGIKVpTVA 23.01 913.570892 6.283E-5 0.06786555979719196 PARK7_HUMAN[28-36] KGGVVGIKVD 44.61 970.581146 -0.001214 -1.2507970147608864 ALDOA_HUMAN[101-110] KIKELQAF 11.87 975.575287 0.003907 4.004816493470687 MMP20_HUMAN[71-78] KIpSGpTVNIR 57.17 986.587265 -0.002761 -2.798536022051734 SYTC_HUMAN[681-689] KLpYEALKF 17.54 1010.580032 0.004782 4.731935966057164 F105A_HUMAN[238-245] KLDApSEpSLR 31.31 1017.545441 -0.002377 -2.3360136110127785 CLH1_HUMAN[1612-1620] =============================================== *Appending miscleavage site sequence contexts* =============================================== With these options: - K as the *amino acid* the protease should have recognized - N-terminal as the side of the recognized amino where the protease should have cleaved. - c6 as *Protein identifier column* - c1 as *Peptide sequence column* - a suitable FASTA database with *Protein sequences* - and everything else set to defaults the example above will generate a result like this:: RAGIKVpTVA 23.01 913.570892 6.283E-5 0.06786555979719196 PARK7_HUMAN[28-36] RRAGIKVTVA KGGVVGIKVD 44.61 970.581146 -0.001214 -1.2507970147608864 ALDOA_HUMAN[101-110] GVVGIKVDKG KIKELQAF 11.87 975.575287 0.003907 4.004816493470687 MMP20_HUMAN[71-78] MIRKIKELQA KLpYEALKF 17.54 1010.580032 0.004782 4.731935966057164 F105A_HUMAN[238-245] LYEALKFIML Note the header line was ignored and if peptides have more than one miscleavage site they will occur more than once in the output. </help> </tool>
