The following table describes the columns in the Results table of the Theoretical Protein/Peptide Manager page.
Column | Description |
|---|---|
Sequence level | |
+/− | Select to show or hide the lower level of precursor information related to the current sequence row. |
(Check box) | Select this checkbox to delete or export only the selected rows in the table. |
Chain | Displays the chain identifier for the peptide sequence. |
Sequence | Displays the amino acid letters and modifications in the peptide sequence. The modifications are surrounded by brackets ("[ ]") and appear to the right of the affected amino acid letter. If there are multiple modifications for one letter, the N-terminal or C-terminal modification appears first, followed by the side chain modification. |
Peptide Mass | Displays the mass of the peptide. |
Modification | Displays the modifications applied to the peptide. If there is no modification, this cell is empty. |
Start Position | Displays the start position of the peptide in the protein sequence where digestion is performed. If you select the Create a Copy checkbox to create a copy of the peptide, the application copies the start position from the original unmodified peptide to display here. |
End Position | Displays the end position of the peptide in the protein sequence where digestion is performed. If you select the Create a Copy checkbox to create a copy of the peptide, the application copies the end position from the original unmodified peptide to display here. |
Precursor level | |
+/− | Select to show or hide the lower level of isotope information related to the current precursor row. |
Precursor Charge State | Displays the charge state number for the precursor. The table displays only the charge states within the range specified in the Charge State Range boxes. |
Precursor m/z | Displays the precursor mass-to-charge ratio. The table displays only the m/z values within the range specified in the m/z Range boxes. |
Isotope level Note: The maximum number of isotopes is from the Number of Isotopes parameter setting. | |
Target m/z | Displays the target mass-to-charge ratio of an isotope. |
Type | Displays the isotope type. |
