Collision-induced dissociation of protonated tetrapeptides containing beta-alanine, gamma-aminobutyric acid, epsilon-aminocaproic acid or 4-aminomethylbenzoic acid residues
(John Wiley and Sons, 2006-01-01)The influence of the presence and position of a single beta-alanine, gamma-aminobutyric acid, epsilon-aminocaproic acid or 4-aminomethylbenzoic acid residue on the tendency to form b(n)+ -and y(n)+ -type product ions was ... -
Influence of "alternative" C-terminal amino acids on the formation of [b3 + 17 + Cat]+ products from metal cationized synthetic tetrapeptides
(John Wiley and Sons, 2004-05-01)The aim of this study was to investigate the dissociation patterns, and in particular the relative abundance of [b(3) + 17 + Cat](+), for peptides with C-termini designed to allow transfer of the -OH required to generate ... -
Isotope labeling and theoretical study of the formation of a3* ions from protonated tetraglycine
(Springer, 2006-12-01)Extensive 13C, 15N, and 2H labeling of tetraglycine was used to investigate the b3+ --> a3* reaction during low-energy collision-induced dissociation (CID) in a quadrupole ion-trap mass spectrometer. The patterns observed ...
