Files to Download from MEROPS
These files are offered for downloading by the users of MEROPS. Most of the files are compressed, and can be expanded with a utility such as WinZip.
1. MEROPS Release 9.8
The large file "meropsweb98.tar.gz" is a compressed version of all the SQL statements required to build a MySQL instance of the current release of the MEROPS database. Some functions such as the Searches and BLAST server are not supported in this format, however.
2. Peptidase and Inhibitor Accession Numbers
The file "dnld_list.txt" contains a non-redundant list of accession numbers, and enables the user to create a library of peptidase and peptidase inhibitor amino acid sequences. Accession numbers are given for all the peptidases for which we have them, but some sequences that have not been deposited inevitably are not included. To retrieve all the sequences, use the GCG command "fetch@filename" (where "filename" is the name of the text file). Alternatively, use the file of accession numbers as a reduced data set for searching with FastA. When prompted for the database name enter "@filename" instead. Included in each line after the exclamation mark are identifiers for peptidase family and species of organism that allow filtering of the data. The organism identifier is that from the NCBI Taxonomy database shown on each organism card in MEROPS.
3. Peptidase Protein Sequences
The file "pepunit.lib" is a non-redundant library of protein sequences in FastA format the peptidase units and inhibitor units of all the peptidases and peptidase inhibitors that are included in MEROPS. The library can be searched by use of FastA without further modification, but must be converted and indexed for BLAST searches. The restriction of the library to peptidase and inhibitor units should decrease the risk of false positive matches to other domains.
4. Peptidase Full-length Sequences
The file "protease.lib" is a non-redundant library of protein sequences in FastA format for all the peptidases and peptidase inhibitors included in MEROPS. The library can be searched by use of FastA without further modification, but must be converted and indexed for BLAST searches.
