Question

The enzyme which specifically catalyzes β (1 → 4) glycosidic linkages of NAM (N-acetyl muramic acid) and NAG (N-acetyl glucosamine) present in bacterial peptidoglycan is _______________

(a) protease

(b) lipase

(c) lysozyme

(d) cellulase

I have been asked this question in unit test.

Question is taken from Extraction of Enzymes by Chemical Methods topic in portion Enzyme Extraction and Isolation of Enzyme Technology

Answer 1

Right option is (c) lysozyme

The explanation is: Lysozyme is an enzyme which catalyzes the β (1 → 4) glycosidic linkages of NAM (N-acetyl muramic acid) and NAG (N-acetyl glucosamine) present in bacterial peptidoglycan. Proteases catalyzes the breakdown of proteins into smaller peptides or single amino acids. Lipase catalyzes the hydrolysis of fats. Cellulase catalyzes the breakdown of cellulose and other polysaccharides to monosaccharides.
