Uses
Biotinylated D-lysine (BDL) can be used to conjugate a biotin handle into bacterial peptidoglycan (PG) for various applications. For example, Suzanne Walker and coworkers reported that penicillin-binding protein PBP4 of
Staphylococcus aureus could use BDL to biotinylate Lipid I and Lipid II, facilitating assays to measure infamously low-abundance pools of cellular lipid-linked PG precursors. BDL provides a tool for studying other aspects of PG assembly including antibacterial development efforts.
