Abstract

The application of electron capture dissociation (ECD) as an analytical method for determining peptide and protein primary amino acid sequences as well as post-translational modification sites is discussed. A 7.0 and 9.4 T homebuilt Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometers were used to conduct ECD. Multiply-charged cations were generated by microelectrospray ionization and to permit infrared multiphoton dissociation (IRMPD) an ECD dispenser electrode was positioned off-axis. The results show amino acid side-chain cleavages for arginine, histidine, asparagine/glutamine, methionine and lysine residues.
