When an entry in the RESID Database is annotated as a general modification with the same enzymatic activity producing different chemical structures depending on natural variation in the nonproteinaceous substrate or on secondary modifications that do not change the nature of the primary modification, then the PSI-MOD definition for each different instance carries the RESID cross-reference followed by the quoted tag "variant". remark: Annotation note 3 - When an entry in the UniMod database is annotated as a general modification, and one or more instance sites are listed, then the PSI-MOD definition for each different site instance carries the UniMod cross-reference followed by the quoted tag "site". remark: Annotation note 4 - In entries with an isotope indicator in the formula, average masses are meaningless and are assigned the value equal to the monoisotopic mass, but rounded to a lower precision; monoisotopic masses are calculated by using the masses for the indicated isotopes and the most common isotopes for elements without isotope indicators in the formulas. remark: Annotation note 5 - For cross-link modifications, the number following "Cross-link" in the comment record indicates the number of amino acid residues that appear in the origin record, used to check the difference formula and masses. This usage differs from RESID, where the cross-link number indicates the maximum number of peptide chains that can be cross-linked. remark: Annotation note 6 - The synonym cross-reference "PSI-MOD:old name" has been replaced by "PSI-MOD:alternate name". remark: Synonym type - The synonyms that are unique for a PSI-MOD entry are EXACT those synonyms that are assigned to multiple terms are RELATED [Term] id: MOD:00000 name: protein modification def: "Covalent modification of, or a change resulting in an alteration of the measured molecular mass of, a peptide or protein amino acid residue."

Many minor peaks accompanying the main peakmight also beattributed to other oxidation products of the tryptophan such as kynurenine (+4),an unknown by-product found in all oxidized tryptophan patterns (+13),hydroxytryptophan (+16), 3-hydroxykynurenine (+20) andhydroxy-N-formylkynurenine (+48).
