remark: Annotation note 1 - "[PSI-MOD:ref]" is to be replaced by the PubMed Id of the PSI-MOD paper when it is available.
remark: Annotation note 2 - When an entry in the RESID Database is annotated with different sources because the same modification can arise from different encoded amino acids, then the PSI-MOD definition for each different source instance carries the RESID cross-reference followed by the quoted tag "resulting". 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remark: Annotation note 6 - The synonym cross-reference "PSI-MOD:old name" has been replaced by "PSI-MOD:alternate name".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

Hydrogen bonding occurs between every other C=O from one strand to every other N-H on the adjacent strand. In this case, if two atoms C-alpha (i)and C-alpha (j) are adjacent in two hydrogen-bonded beta strands, then they do not hydrogen bond to each other; rather, one residue forms hydrogen bonds to the residues that flank the other (but not vice versa). For example, residue i may form hydrogen bonds to residues j - 1 and j + 1; this is known as a wide pair of hydrogen bonds.

Kim and Raines using ESI-MS and sulfhydryl group titration found that bovine seminal ribonuclease contains a single oxidized sulfhydryl group, which cannot participate in a disulfide bond. This form of cysteine is called sulfenic acid (-SOH).

comment: From DeltaMass: Average Mass: -17 Abbreviation:Otc Average Mass Change:-17 References:J. Proteome Res. 1, 181-187 (2002) Notes:A secondary modification affecting peptides with S-carbamoylmethyl-L-cysteine (CamC) at the N-terminus. These exist in enzymatic digests of proteins that have been S-alkylated with iodoacetamide. In a reaction that parallels the formation of N-terminal 2-oxopyrrolidine-5-carboxylic acid (also called pyroglutamic acid, 5-oxoproline or 2-pyrrolidone-5-carboxylic acid) from N-terminal glutamine, cyclization of N-terminal CamC gives an N-terminal residue of (R)-5-oxoperhydro-1,4-thiazine-3-carboxylic acid. Peptides in which this has occurred become more hydrophobic, and lose 17 Da from the N-terminal residue.

def: "modification from UniMod Artifact" [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.

comment: From DeltaMass: Average Mass: -34 Average Mass Change:-34 Notes: 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). All known batcterially 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 relative 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. Dehydroalanine is not known to be produced naturally by loss of hydrogen sulfide from cysteine. (JSG)

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.

It is suggested that the formationof these side products is attributable to the generation offormaldehyde, during removal of the histidine protecting group(benzyloxymethyl), which reacts with the N-terminus of the peptideto 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 isclear that the combined strategy of derivatization and tandem massspectrometry has allowed structural conclusions concerningindividual components of an isobaric mixt.

AUTHOR(S) Misra DPSOURCE (BIBLIOGRAPHIC CITATION)J-Clin-Pathol.1975 Apr; 28(4): 305-8.INTERNATIONAL STANDARD SERIAL NUMBER 0021-9746 ABSTRACT The crosslink in bone collagen was analysed in specimens of bone obtained atnecropsy from cases of Paget's disease and compared with normal bone collagenof the same age. The specimens were stored at -20 degrees C before analysis.The predominant crosslink in a normal bone collagen was hydroxylysinohydroxynorleucine (di OH-LNL) (F1), which was designated syndesine in the past; another fraction, hydroxylysinorleucine (HLNL) (F2),musch less prominent than di OH-LNL, was also noted in a normal bone collagen.Both fractions were reduced in bone tissue of advancing age. The peakcorresponding to HLNL was considerably increased in Paget's disease. This abnormality was constantly seen in specimens of bone from cases of Paget'sdisease, but the significance of the finding could not be assessed from the present investigation. Calcitonin has been shown to produce complete remission in Paget's disease and the crosslink pattern was found to be normal in specimens examined froma calcitonin-treated patient. This shows that calcitonin has some effect on the metabolism of collagen and a normal crosslink in such a situation lends support to this idea. PubMed:75151974.

comment: From DeltaMass: Average Mass: 13 Formula:C2H2O2 vs C3H5ON Monoisotopic Mass Change:13.03 Average Mass Change:13.05 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 iodoacetic acid e.g. in preparation for proteomic analysis, will convert remaining free cysteines into carboxymethyl-Cys (CM-Cys, DeltaMass +58Da; see entry). Peptide mass fingerprinting may therefore potentially reveal the same cysteine-containing peptide in two forms, differing in mass by 13Da. 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.

comment: From DeltaMass: Average Mass: 15 Average Mass Change:15 Notes:In going from Lys to hydroxy-allysine, two separate reactions are involved:1. the oxidative deamination converting Lys to allysine (-CH2NH2 being converted to -CHO) with a net mass change of -1;2.conversion of allysine to delta-hydroxy-allysine (-CH2-CHO being converted to -CH(OH)-CHO) with a mass change of +16. The net change from Lys to hydroxyallysine thus is +15.

def: "modification from DeltaMass" [DeltaMass:345]
comment: 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.

comment: From DeltaMass: Average Mass: 67 Average Mass Change:67 References:http://www.abrf.org/archives/hmail/0008/0007.html Notes:1.) 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.

comment: Cross-link 2. This modification destroys a cross-link. From DeltaMass: Average Mass: 98 Abbreviation:Cya Average Mass Change:98 Notes:Treatment of cystine by strongly oxidising reagents such as performic acid results in the breakage of the disulphide bond and complete oxidation of the sulphur atoms on each molecule. Such treatment is often carried out prior to amino acid analysis as the resulting cysteic acid is then resistant to acid degradation during the hydrolysis procedure.

comment: From DeltaMass: Average Mass: 162 Average Mass Change:162 Notes:(from the ABRF discussion list archive) There may be ... things in the reagent K that would allow cleavage of the peptide to occur at the wrong place...in this case it removes the dimethoxybenzyl group first inactivating that site for cleavage, and it goes after tne next amide bond closer to the resin. Try the TFA/TIS/water/EDT cocktail...TFA = 92%, TIS =3%, and water is at 5%. .. had this issue on longer peptides.. and by increasing the amount of water a little bit... able to elminate this problem.

comment: CAUTION, peptides of 2-hydroxyglycine are known to be unstable, decaying to break the peptide backbone and form peptidyl amides [see J. Am. Chem. Soc. 111, 1933-1934, 1989, and J. Org. Chem. 57, 3916-3921, 1992]. If computer analysis of tandem mass-spectrometric results predicts this modification, then it is most probable that there are multiple isobaric peptides differing in the location of multiple hydroxylation modifications.

comment: CAUTION, observations of this modifation are attributable to artifacts produced in preparation. It is extremely unlikely that eukaryotes produce this modification, because an enzyme acting to form the methyl ester of L-aspartyl peptides would interfere with the D-aspartyl peptide repair mechanism.
