Oxidized amino acid residues in human serum albumin exposed to hydrogen peroxide have been identified in tryptic peptides using liquid secondary ion mass spectrometry. Sites of oxidation identified include Cys34, Met123, Met298, Met446, and Met548. The extent of oxidation varied with location in the protein sequence, suggesting a relationship between(More)
The diversity of the gamma subunits in bovine brain G protein preparations was investigated using matrix-assisted laser desorption ionization (MALDI) mass spectrometry. Analysis of these G protein mixtures revealed at least four gamma subunit masses by the following four criteria. 1) The measured masses were in the same mass range as the predicted molecular(More)
