Abstract: Utilizing microscale chemical derivatization reactions and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, we have identified a novel posttranslational modification of aspartic acid, beta-methylthio-aspartic acid. The modified residue is located at position 88 in ribosomal protein S12 from Escherichia coli, a phylogenetically conserved protein that has been implicated in maintaining translational accuracy of the ribosome. |
