    Abstract

    The identification and characterization of biotinylated lysyl residues in a polypeptide chain by automated sequence analysis is described. An in depth analytical study was conducted for the delineation of Nε{lunate} modification of lysyl residues with N-hydroxysuccinimide esters of biotin and 6-aminohexanoic biotin. Confirmation of the structure of the phenylthiohydantoin derivatives of Nε{lunate} biotinylated lysine was achieved by mass spectrometry. The analytical study focused on the identification of biotinylated lysine-4 of neuropeptide Y which served as a model peptide for the analytical procedures detailed.
