2. Peptidoglycan - Wikipedia

   en.wikipedia.org/wiki/Peptidoglycan

   Peptidoglycan. The peptidoglycan layer within the bacterial cell wall is a crystal lattice structure formed from linear chains of two alternating amino sugars, namely N-acetylglucosamine (GlcNAc or NAG) and N-acetylmuramic acid (MurNAc or NAM).

3. Penicillin-binding proteins - Wikipedia

   On the other hand, class B enzymes possess transpeptidase activity (only cross linking). Low Molecular-Mass (LMM) PBP’s are dispensable for normal cell growth and control how tightly the peptidoglycan chains are linked together. [5] Proteins that have evolved from PBPs occur in many higher organisms and include the mammalian LACTB protein. [6]

4. DD-Transpeptidase - Wikipedia

   en.wikipedia.org/wiki/DD-transpeptidase

   DD-Transpeptidase is the target protein of β-lactam antibiotics (e.g. penicillin). This is because the structure of the β-lactam closely resembles the D -ala- D -ala residue. β-Lactams exert their effect by competitively inactivating the serine DD -transpeptidase catalytic site.

5. Lysozyme - Wikipedia

   en.wikipedia.org/wiki/Lysozyme

   Lysozyme (EC 3.2.1.17, muramidase, N-acetylmuramide glycanhydrolase; systematic name peptidoglycan N-acetylmuramoylhydrolase) is an antimicrobial enzyme produced by animals that forms part of the innate immune system. It is a glycoside hydrolase that catalyzes the following process:

6. Polypeptide antibiotic - Wikipedia

   en.wikipedia.org/wiki/Polypeptide_antibiotic

   Bacitracin is a polypeptide antibiotic derived from a bacterium, Bacillus subtilis, and acts against bacteria through the inhibition of cell wall synthesis. [6] It does this by inhibiting the removal of phosphate from lipid compounds, thus deactivating its function to transport peptidoglycan; the main component of bacterial cell membranes, to the microbial cell wall.

7. Peptidoglycan glycosyltransferase - Wikipedia

   en.wikipedia.org/wiki/Peptidoglycan_glycosyl...

   Peptidoglycan glycosyltransferase (EC 2.4.1.129) is an enzyme used in the biosynthesis of peptidoglycan. It transfers a disaccharide-peptide from a donor substrate to synthesize a glycan chain. [1] This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases.
