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, on secondary modifications that do not change the nature of the primary modification, or on a combination of a primary and one or more secondary modifications on the same residue, then the PSI-MOD definition for each different instance carries the RESID cross-reference followed by the special tag "#var". remark: Annotation note 03 - 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 a hash symbol and an amino acid code, "N-term" or "C-term". remark: Annotation note 04 - The elemental formulas are in strict alphabetical order, not in CAS ("C" and "H" first) order. Isotope numbers are in parentheses before the element symbol, and an element should not occur in a formula both with and without an isotope number. In difference formulas, counts can be zero or negative. remark: Annotation note 05 - 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 other elements without isotope indicators in the formulas. remark: Annotation note 06 - 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 remark: Annotation note 07 - The synonym cross-reference "MOD:old name" has been replaced by "MOD:alternate name". remark: Annotation note 08 - The DeltaMass listings for free amino acids have been removed. Most Unimod entries that have not been "approved" have by general agreement not been incorporated unless there has been a request for a specific term by a PRIDE submitter. remark: Annotation note 09 - The Open Mass Spectrometry Search Algorithm, OMSSA, enumerated list of modifications are being incorporated. The string values are synonyms with the synonymtypedef "OMSSA-label", and their integer values (which are supposed to be stable) are definition cross-references. remark: Annotation note 10 - GNOme is the Glycan Naming and Subsumption Ontology (https://gnome.glyomics.org/), an ontology for the support of glycomics. PSI-MOD does not have all possible glycans in its entries, just the ones that are noted to be on proteins and have been requested for addition. GNOme uses GlyTouCan (http://glytoucan.org/) to provide stable accessions for glycans described at varyious degrees of characterization, including compositions (no linkage) and topologies (no carbon bond positions or anomeric configurations). idspace: uniprot.ptm https://bioregistry.io/uniprot.ptm: "UniProt Post-Translational Modification" [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."

[DeltaMass:235, PubMed:8597590, Unimod:276] comment: From DeltaMass: Average Mass: 183 Average Mass Change:183 References:We have found that AEBSF modifies many proteins by covalent attachment, preferentially on Tyr, and to a lesser extent on Lys, His, and the amino-terminus. These modifications were identified by electrospray MS of the proteins (adds 183 Da per AEBS-group) and by peptide mapping and MS/MS. All the proteins we examined were modified after 24 hrs. at 4 C with 1 mM AEBSF in TRIS, pH 8.0. The reaction is 10-20x slower at pH 7; however AEBSF is quite stable in aqueous solution and the extent of to which the protein is modified continues to increase for several days. We have seen the addition of 10 or more AEBS-groups to proteins after prolonged storage. We found no equivalent modification from PMSF, probably because it degrades so quickly. We no longer use AEBSF, and urge caution to those who do. To address the problem, Boehringer Mannheim (now Roche Molecular Biochemicals) introduced Pefabloc PLUS which includes an additional component to compete for these side reactions. In our limited experience with Pefabloc PLUS, it reduces the +183 modifications, but does not always eliminate them. As a result, we prefer PMSF, despite its own set of drawbacks. We have never found PMSF-induced modification of proteins (except trypsin), probably due to its short half-life in aqeous solution. synonym: "AEBS" RELATED PSI-MS-label [] synonym: "AEBSF" EXACT DeltaMass-label [] synonym: "Aminoethylbenzenesulfonylation" RELATED Unimod-description [] xref: DiffAvg: "183.23" xref: DiffFormula: "C 8 H 9 N 1 O 2 S 1" xref: DiffMono: "183.035400" xref: Formula: "none" xref: MassAvg: "none" xref: MassMono: "none" xref: Origin: "X" xref: Source: "artifact" xref: TermSpec: "none" xref: Unimod: "Unimod:276" is_a: MOD:01652 ! sulfonyl halide reagent derivatized residue [Term] id: MOD:00597 name: methyl methanethiosulfonate def: "OBSOLETE because Unimod entry 277 redundant with Unimod 39.

I imagine one can think of it as a condensation of cysteine and dehydroalanine but I do not know how it is made biologically. Dehydroalanine could be derived from either serine or cysteine. If I recall Biochem 101 correctly lanthionine was first found in wool.-Lowell Ericsson (ERICSSONLH@U.WASHINGTON.EDU)As far as I know, the structure of lanthionine is two Ala's joined by a single sulphur with the loss of two hydrogens from the methyl group of the Ala.Stephen Bayne (sbay@novo.dk)Regarding the structure of lanthionine and dehydroalanine: dehydroalanine is formed by the loss of one sulfur atom and two hydrogen atoms from ONE cysteine residue. lanthionine is formed from TWO cysteines, is a thioether, and contains one sulfur atom less than the amino acid cystine. Dan McCormick (MCCORMICK@rcf.mayo.edu) [DeltaMass]. Most bacterially produced lanthionine crosslinks are made by dehydration of L-serine to dehydroalanine, and then reaction with L-cysteine so as to produce chiral inversion at the alpha-carbon of the original L-serine; the lanthionine is a meso-diastereomer with L-configuration of the original cysteine alpha-carbon and D-configuration of the original L-serine alpha-carbon. In cypemycin dehydroalanine has been shown to be produced by loss of hydrogen sulfide from cysteine. Beta-elimination of hydrogen sulfide does occur during treatment with performic acid [JSG]. subset: PSI-MOD-slim synonym: "2,3-didehydroalanine" EXACT RESID-alternate [] synonym: "2-aminoacrylic acid" EXACT RESID-alternate [] synonym: "2-aminopropenoic acid" EXACT RESID-systematic [] synonym: "4-methylidene-imidazole-5-one (MIO) active site" EXACT RESID-alternate [] synonym: "anhydroserine" EXACT RESID-alternate [] synonym: "Cys->Dha" RELATED PSI-MS-label [] synonym: "dehydroalanine" EXACT RESID-name [] synonym: "Dehydroalanine (from Cysteine)" EXACT DeltaMass-label [] synonym: "Dehydroalanine (from Cysteine)" RELATED Unimod-description [] synonym: "Dha" EXACT RESID-alternate [] synonym: "dHAla(Cys)" EXACT PSI-MOD-label [] synonym: "MOD_RES 2,3-didehydroalanine (Cys)" EXACT UniProt-feature [] xref: DiffAvg: "-34.08" xref: DiffFormula: "C 0 H -2 N 0 O 0 S -1" xref: DiffMono: "-33.987721" xref: Formula: "C 3 H 3 N 1 O 1" xref: MassAvg: "69.06" xref: MassMono: "69.021464" xref: Origin: "C" xref: Source: "natural" xref: Unimod: "Unimod:368" xref: TermSpec: "none" xref: uniprot.ptm:PTM-0468 is_a: MOD:00905 ! modified L-cysteine residue is_a: MOD:01168 ! dehydroalanine [Term] id: MOD:00794 name: pyrrolidone from proline def: "OBSOLETE because redundant and identical to MOD:00477.

Get rid of the DBU. It can cause piperidine amides at Asp residues. The tbu ester side chain comes off during synthesis and the residue is trans-amidated with piperidine (+67Da by MS). If you haven't yet seen this, you will. Even "normal" 20% pip/DMF (NMP) will cause this, but less frequently. Literature exists for this; I don't remember the exact reference. David H.

The reporter group, an isotopically labeled 1,4-dimethylpiperazine, is connected to a carbonyl balance group that is isotopically labeled to produce a nominally isobaric combined modification.
