The mechanism by which lysozyme exerts its antibacterial effects is multifaceted. Primarily, it functions as a muramidase, a glycoside hydrolase that catalyzes the hydrolysis of the $\beta$-(1→4) glycosidic bond between N-acetylmuramic acid (NAM) and N-acetylglucosamine (NAG) residues in the peptidoglycan layer of bacterial cell wallsLysozyme is antibacterialthrough these two mechanisms. The peptidoglycan(PG) skeleton of bacterial cell wall is connected by NAG and NAM through peptide .... This enzymatic action weakens the structural integrity of the cell wall, leading to cell lysis. This mode of action is particularly effective against Gram-positive bacteria due to their thick peptidoglycan layer.
