It is resistant to proteases because it contains D-amino acids, but lysozyme can break down its beta-1-4 linkages between repeating units of N-acetyl-muramic acid and N-acetyl-glucosamine.  
The monomers of this substance are moved to their final destination bound to the carrier bactoprenol.  It is resistant to proteases because it contains D-amino acids, but lysozyme can break down its beta-1-4 linkages between repeating units of N-acetyl-muramic acid and N-acetyl-glucosamine.  It is the target of some antibiotics, including penicillin, which blocks the action of the enzymes responsible for crosslinking the polysaccharide chains via tetrapeptides.  FTP name this polymer that accounts for 90% of the dry weight of Gram-positive bacteria, the primary constituent of bacterial cell walls.
