Collisional activation of [M + H](+) parent ions from peptides of n amino acid residues may yield a rearrangement that involves loss of the C-terminal amino acid residue to produce (b(n-1) + H(2)O) daughters. We have studied this reaction by a retros

In an ion cyclotron resonance (ICR) cell, Mo(CO)n+ ions (n = 0–6), generated by electron ionization (EI) with 70 eV electrons, on collisions with Mo(CO)6 undergo charge exchange (confirmed by isotopic experiments), collision-induced dissociation (C

IclR protein, the repressor of the aceBAK operon of Escherichia coli, has been examined by time-of-flight mass spectrometry, with ionization by matrix assisted laser desorption or by electrospray. The purified protein was found to have a smaller mass

Time-of-flight correlation methods have been used to determine the primary structure of the major component in a nonstandard preparation of alamethicins, and to give some sequence information about minor components. The peptide (MW ≈ 2000 u) is blo
