Used in biochemical research as a modified amino acid for studying enzyme activity and protein modification. Acts as a substrate analog in investigations of lysine-specific enzymes, particularly in deacetylase and demethylase assays. Its furanyl-containing side chain enables detection in metabolic labeling experiments. Employed in the development of inhibitors targeting post-translational modification enzymes. Also utilized in synthetic pathways for creating peptide-based probes with enhanced binding specificity.
