1. Main menu
See detailed description of the Protein main menu under 5. Proteins.
- 1.1.1. Proteins: Currently available complete Poaceae prolamin sequences from Uniprot and links to reference databases (NCBI and Uniprot). Sequences belonging to the same type manually double checked for annotations and corrected based on multiple sequence alignments and characteristic N- and C-terminal sequences (e.g. entry is assigned as LMW-glutenin but based on sequence characteristics it is a gamma-gliadin). Signal peptides were not removed. See detailed description of the Protein submenu under 5.1. Proteins.
- 1.1.2. GenBank: This table shows nucleotid information related to the protein entry. See detailed description of the Related nucleotids submenu under "5.2.GenBank".
Specific in silico digested peptide entries obtained from the above described proteins using single or multiple enzymatic cleavage tools. Enzymes were trypsin, chymotrypsin-low specificity, pepsin-pH 1.3, LysC, Thermolysin and Proteinase K. See detailed description of the Peptide main menu under 6. Peptides.
Epitopes obtained from IEDB database using a filter of Poaceae x Homo sapiens and this database was completed with core celiac specific epitopes reported in literature up to date. See detailed description of the Epitopes main menu under 7. Epitopes.
This menu provides direct access to cross searches, which function can be available through Base search, too.
The following connections are available:
2. Records per page
Changing the number in the textbox, the number of entries to be displayed can be selected. Various sets of entries can be displayed by selecting one of the display options below the tables, i.e.
3. Search and filter boxes
There are more search boxes can be used in ProPepper. The upper search box
Filter: above the table is for general search across the full content of the table, while search boxes under column headers are for specific searches only applicable in that column. Results will appear showing all the corresponding data in a row, not only that column.
4. Up and down arrows in column headers
Clicking on the arrows in the right hand side of the column header, the entries can be sorted in forward or reverse alphabetical order.
Headers and some entries are equipped with tooltips, hovering the mouse over a header or data entry, the full name, sequence or description will be shown if available.
Identical entries in a column suggest some differences in any of the related column(s). For example, the same sequence is shown in more rows if that sequence belongs to more organisms or genotypes.
