Step #1 : Enter Your Search Parameters
SPdb provides a few ways to query for results. You can search by Swiss-Prot entry name or accession number if you know it. Otherwise you can search by inserting a sequence or organism name. Please enter only 1 of the 3 search fields.
Swiss-Prot Entry Name / Accession No.:
Name of Organism :
Sequence to search :
Step #2 : Select the filtering options
In this step, you can choose options available to limit your search results and also other filtering options.
(i) You can choose to search through either the filtered or unfiltered dataset.
Data filtering :
Filter out experimentally unverified sequences. (including those with more than 1 possible end positions)
(ii) You can search within the different groups : archaea, bacteria, eukaryotes, viruses or all the groups.
(iii) You can choose to limit the length of the signal sequences that you're searching. Please note that based on the data we have, we have omitted sequences which are less than 11 residues if you've selected the filtered data. Otherwise, you can search by any length.
Sequence Length :
(if data filtering is selected, signal sequences less than 11 residues are omitted by default.)
(iv) You can select the number of entries you want to view per page on the result page. The minimum is 10 entries per page and maximum is 50 entries per page.
Display Results :
entries per page
Step #3 : View Results
After you have completed step 2 and entered all the parameters, the results will be output either as web page or as a downloadable zipped file containing the signal sequences depending the option that you have selected.
