Development of an electrospary ionization source and vacuum interface for guided ion beam tandem mass spectrometry experiments: structural and energetic effects in the molecular recognition of amino acids by 18-crown-6
… proteins were determined in a step by step fashion using guided ion beam tandem mass spectrometry techniques. Firstly, 18C6 binding affinities of several peptidomimetic bases (B) that serve as mimics of the side chains of Lys, Arg, and His and n-terminal amino group have been examined to provide …

Noncovalent Interactions Between Alkali Metal Cation And Aza/thia-Crown Macrocycles: Mass Spectrometric Techniques And Theoretical Studies
… experimental and theoretical description of cation-aza-crown and thia-crown ether interactions with alkali metal cations. Infrared multiple photon dissociation (IRMPD) action spectroscopy and energy-resolved collision-induced dissociation (CID) techniques were used in conjunction with …

Consequences of Oxidative DNA Damage: Base-Pair Dissociation, Singlet Oxygenation and DNA-Protein Crosslinking
… (OG) is a common DNA lesion resulting from oxidatively generated damage and pairs with complementary cytidine (C) in Watson Crick base-pairing within duplex DNA. The WC-OG·C lesion, if not recognized or repaired, not only leads to G⋅C→T⋅A transversion mutations (through …
