SHORT COMMUNICATION Electron Transfer Dissociation of Peptide Anions
Ion/ion reactions of multiply deprotonated peptide anions with xenon radical cations result in electron abstraction to generate charge-reduced peptide anions containing a free-radical site. Peptide backbone cleavage then occurs by hydrogen radical abstraction from a backbone amide N to facilitate cleavage of the adjacent COC bond, thereby producing aand x-type product ions. Introduction of free...
متن کاملPeptide and protein quantification using iTRAQ with electron transfer dissociation.
Electron transfer dissociation (ETD) has become increasingly used in proteomic analyses due to its complementarity to collision-activated dissociation (CAD) and its ability to sequence peptides with post-translation modifications (PTMs). It was previously unknown, however, whether ETD would be compatible with a commonly employed quantification technique, isobaric tags for relative and absolute ...
متن کاملHighly efficient and switchable electron-transfer system realised by peptide-assisted J-type assembly of porphyrin.
We propose a new strategy for fabrication of a phase-separated bicontinuous system composed of low-molecular donor and acceptor that is built up through coordination-based orientation of pyridylated fullerene on a π-conjugated zinc-porphyrin J-type assembly. This complex system exhibits extremely efficient and switchable fluorescence quenching.
متن کاملIntrinsic dissociation constants of aspartyl and glutamyl carboxyl groups.
The synthesis of N-acetyl-L-isoasparagine and of N-acetylL-isoglutamine is reported. The acid dissociation constants of these compounds, and those of their corresponding Ncarbobenzoxy derivatives, have been measured. Since these compounds are uncharged molecules of the type -NH-CH(-CH,COOH)-COor the corresponding glutamyl homologue, their dissociation constants represent the intrinsic dissociat...
متن کاملHighly efficient photolabile protecting groups with intramolecular energy transfer.
DNA chips are widely used for genomic analysis. Currently, high-density DNA chips can be synthesized with up to several hundred thousand different spots on an area of 1 cm. In principle, the complete human genome can be probed with such a chip. The required high spot densities can be achieved by photolithographic in situ DNA-chip synthesis. In this method, the oligonucleotides are synthesized s...
