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 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 a hash symbol and an amino acid code, "N-term" or "C-term". remark: Annotation note 4 - 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 5 - 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 6 - 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 remark: Annotation note 7 - The synonym cross-reference "MOD:old name" has been replaced by "MOD:alternate name". remark: Annotation note 8 - 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 9 - 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.

[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" 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: TermSpec: "none" 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.

Mass Spectrom. 3(9), 314-19 Notes: Fast-atom bombardment mass spectrometry of a synthetic renin substrate decapeptide (Pro-His-Pro-Phe-His-Leu-Val-Ile-His-D-Lys) indicated the presence of several side products, including a component 12 Da higher in mass. Low-energy collisionally activated ***decompn*** analyses were performed using a hybrid tandem instrument and demonstrated that the heavier side product had two components, in which the structural modification was either at the N- or the C-terminus. Addnl. analyses of the N-acetyl deriv. indicated that for each component the structural modification blocked a site of N-acetylation. It is suggested that the formation of these side products is attributable to the generation of formaldehyde, during removal of the histidine protecting group (benzyloxymethyl), which reacts with the N-terminus of the peptide to give an imidazolidinone structure or with the D- ***lysine***.epsilon.-amine group to yield an ***imine*** .
