NAG

Transpeptidation reaction is the chemical reaction that forms the peptide cross-links or bonds during the synthesis of peptidoglycan (murein) in a bacterial cell wall. Peptidoglycan or murein is a polysaccharide molecule that consists mainly of alternating repeats of N-acetylglusamine (NAG) and N-acetylmuramic acid (NAM). Murein is a bacterial cell wall polymer that contains short peptide […]
