D-aspartyl and L-asparaginyl residues coupled in sequence and cyclised by condensation of the side-chain amino group of the L-lysyl residue with the C-terminal carboxylic acid group. It is the major component of bacitracin. It has a role as an antibacterial agent and an antimicrobial agent. It is a homodetic cyclic peptide and a polypeptide."}]
