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.

The normal biological process involves formation of an amide of an amino acid residue in a peptide sequence where it is followed by a glycine and two basic residues, either arginine or lysine, although in some taxa only one basic residue is required. The peptide is cleaved after the basic residues, glycine is oxidized to hydroxyglycine, which decomposes to release a carboxamide C-terminal [JSG].

CAM-Cys vs PAM-Cysc back to ToC or Class ToC

IRI: http://purl.obolibrary.org/obo/MOD_00969

From DeltaMass: Average Mass: 14 Formula:CH2 Monoisotopic Mass Change:14.016 Average Mass Change:14.027 Notes: Residual acrylamide in SDS gels can partly label cysteine residues in proteins (propionamido-Cys, PAM-Cys, DeltaMass +71Da; see entry). Subsequent alkylation of protein bands with iodoacetamide e.g. in preparation for proteomic analysis, will convert remaining free cysteines into carboxamidomethyl-Cys (CAM-Cys, DeltaMass +57Da; see entry). Peptide mass fingerprinting may therefore potentially reveal the same cysteine-containing peptide in two forms, differing in mass by 14Da. The relative ratios of the peaks will depend on the initial degree of labelling with acrylamide. Use of high quality, deionised acrylamide in the SDS gel will minimise modification of cysteine through this route. Where it remains a problem, deliberate alkylation using acrylamide instead of iodoacetamide will ensure chemical homogeneity of the final product.

The deamidation and methylation of L-asparagine has not been reported as a natural modification. It is extremely unlikely that eukaryotes produce this modification, because a natural process that would form L-aspartic acid 4-methyl ester from either L-aspartic acid or L-asparagine would interfere with the D-aspartyl peptide repair mechanism [JSG].

From DeltaMass: In an attempt to clarfiy the difference between the modification of cysteine to lanthionine and cysteine to dehydroalanine, the following contributions from the ABRF email forum are presented:Structurally speaking lanthionine is like cystine but lacks one S atom. 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].

Protein Sci (1996) 5, 524-530 Mass spectrometric-based revision of the structure of a cysteine-rich peptide toxin with gamma-carboxyglutamic acid, TxVIIA, from the sea snail, Conus textile. Notes: The elimination of CO2 will regenerate glutamate as if there was no modification. However, peaks appearing with an interval of 44 is quite characteristic. It would be noteworthy to remind that loss of 44 from a gamma-carboxyglutamate-containing peptide may be observed not only as a result of spontaneous decarboxylation but also as an artifact under some ionization conditions such as negative ion mode MALDI.

(1989) Characterization of impurities in a synthetic renin substrate peptide by fast-atom bombardment mass spectrometry and hybrid tandem mass spectrometry. Rapid Commun. 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*** . While the precise genesis of the side-products remains speculative, it is clear that the combined strategy of derivatization and tandem mass spectrometry has allowed structural conclusions concerning individual components of an isobaric mixt.

At least three protein crystallographic structures have been reported with this modification. However, no chemical evidence for this modification is provided, there were no reports of this modification before these crystallographic reports, and there is no metabolic explanation for the conversion of a formyl group to a carboxy group. There is confusion in its description, and misnaming is common. This modification is probably a misidentification of N-(dihydroxymethyl)methionine, the hydrated form of N-formylmethionine. See MOD:01446 [JSG].

N4-methyl-L-asparagine, see MOD:0079, was found at a homologous position of the same protein in a closely related species. Since the peptide containing this modification was obtained by enzymatic cleavage, not cyanogen bromide cleavage, it could have experienced oxidation of the following methionine residue, leading to the erroneous attribution of a mass of 29 for the modification rather than 14. comment: This is a deprecated entry in RESID.

One glycosylated serine with weak electron density was modeled as O3-alpha-xylosylserine, while O3-alpha-mannosyl serine and threonine were modeled at ten other positions. The authors do not discuss this exception or provide chemical evidence for it. Since an O3-xylosyl serine modification has not been reported in any other fungal proteins, the modification is probably also an O3-alpha-mannosyl serine, see MOD:00810 [JSG].

From DeltaMass: Average Mass: 51 Average Mass Change: 51 References:Lukszo, Patterson, Albericio, and Kates, Letters in Peptide Science 3, 157-166(1996) Notes:The side reaction can be very significant, and the level to which it occurs depends on how the C-terminal Cys is anchored and what the side-chain protecting group is. The mechanism involves piperidine-mediated beta-elimination of sulfur (with the protecting group on), followed by addition of piperidine across the C-terminaldehydroalanine. Since this last-mentioned step creates a chiral center, a mixture of diastereomers is formed which in special cases can be separatedby HPLC. Another problem with C-terminal Cys is racemization; some references in the review article by Andreu, Albericio, Sole, Munson, Ferrer, and Barany in Pennington-Dunn Peptide Synthesis and Purification Protocols, vol 35, 1994, pp. 91-169.

From Unimod. In PubMed:2026710, mono- and diiodination of tyrosine are discussed, but triiodination of tyrosine is not mentioned. In PubMed:15627961, triiodothyronine (see MOD:00186) is discussed, but triiodotyrosine is not mentioned. This modification probably does not exist, and may be a confusion of "tyrosine" for "thyronine", a common error [JSG].
