Detailed explanation-1: -(B) Lysozyme hydrolyzes the -1, 4 glycosidic bond between the NAM of 1 monomer and the NAG of the adjacent monomer. Lysozyme hydrolysis of PG leads to cell wall instability and bacterial cell death.
Detailed explanation-2: -Lysozyme is an enzyme that cleaves peptidoglycan in bacterial cell walls by catalyzing the hydrolysis of -(1, 4) linkages between the NAM and NAG saccharides (Fig. 1B, upper) 3.
Detailed explanation-3: -Lysozyme was shown to be present in human tears and to kill Gram-positive bacteria by Alexander Fleming (Fleming, 1922).
Detailed explanation-4: -Lysozyme, through its dual activities as a lytic enzyme and a small cationic protein, damages or kills bacteria by lysing their cell wall peptidoglycan, by disrupting bacterial membranes, and by activating autolytic enzymes in the bacterial cell wall.
