Question

Lysozyme, an enzyme found in human saliva, tears, and other secretions, catalyzes the hydrolysis of the $\beta-1,4$ -glycosidic linkages in peptidoglycan. Predict the effect of this enzyme on bacteria, and explain the role its activity plays in human health.

How is the enzyme lysozyme, found in tears and other body fluids, a barrier to pathogens? The enzyme triggers a response from genes to signal cytokines. The enzyme can program cells to self-destruct. The enzyme attacks the cell walls of gram-positive bacteria. The enzyme contains mucin, which chemically destroys invading pathogens. The enzyme can phagocytose large bacteria.

Lysozyme is an enzyme that breaks down bacterial cell walls and is found in your tears, mucus, and saliva. A mutation occurs in the gene for lysozyme that results in a lysine (a positively charged amino acid) being substituted for an arginine (also a positively charged amino acid). Do you think that the mutant lysozyme will function similarly to the normal lysozyme? Explain why or why not?

Lysozyme For the enzyme, answer: a- is it encoded by viral or bacterial genes? (In other words, is it a bacterial or viral enzyme?) b- what is the function of the enzyme? c- does it contribute to the lytic or lysogenic cycle?

00:01 The bacterial cells, these cells are protected by the peptidoglycan layer.
00:09 And this peptidoglycan, it has two units, the inacetyl myuramic acid or nam and the inacetyl glucosamine or nam.
00:20 Now the enzyme lysosine that is present in human tears saliva, this enzyme causes the hydrolysmine.
00:30 Of the beta 1 -4 glycosidic bond and this bond is present between the n -acetyl myromic acid of 1 peptide glycine monomer and the inacetyl glucosamine of the the adjacent peptidoglycan monomer...
