Transient Conformations Leading to Peptide Fragment Ion [c + 2H]+ via Intramolecular Hydrogen Bonding Using MALDI In-source Decay Mass Spectrometry of Serine-, Threonine-, and/or Cysteine-Containing Peptides
Autor: Mitsuo Takayama
Publikováno v: Molecules, Vol 28, Iss 23, p 7700 (2023)
The formation of a peptide fragment ion [c + 2H]+ was examined using ultraviolet matrix-assisted laser desorption/ionization in-source decay mass spectrometry (UV/MALDI-ISD MS). Unusually, an ISD experiment with a hydrogen-abstracting oxidative matri

Sensitive and resistant of the homologous disulfide-bridged proteins α-lactalbumin and lysozyme to attack of hydrogen-atoms, dithiothreitol and trifluoroacetic acid, examined by matrix-assisted laser desorption/ionization mass spectrometry
Autor: Mitsuo Takayama
Publikováno v: Biochemistry and Biophysics Reports, Vol 29, Iss , Pp 101212- (2022)
Background: Evolutionarily homologous proteins bovine α-lactoalbumin (αLA) and hen egg-white lysozyme (HEL) are very similar in primary, secondary and tertiary structures involving the location of disulfide-bridges (S–S), and are resistant to the

Complete and selective nitration of tyrosine residue in peptides caused by ultraviolet matrix-assisted laser desorption/ionization
Autor: Mitsuo Takayama
Publikováno v: Photochemicalphotobiological sciences : Official journal of the European Photochemistry Association and the European Society for Photobiology.
Complete and highly selective nitration of tyrosine (Tyr) as a residue-specific modification in peptides was found without side reactions, using ultraviolet matrix-assisted laser desorption/ionization (UV-MALDI) with a nitroaromatic reagent 3, 5-dini

Multiple Hydrogen Loss from [M + H]+ and [a]+ ions of Peptides in MALDI In-Source Decay Using a Dinitro-Substituted Matrix
Autor: Mitsuo Takayama, Kei Miyazawa
Publikováno v: Journal of the American Society for Mass Spectrometry. 31:547-552
The formation and radical-directed dissociation of multiple hydrogen-abstracted peptide cations [M + H – mH]·+ has been reported using MALDI-ISD with dinitro-substituted matrices. The MALDI-ISD of ...
