1. Lysozyme

   Lysozyme (EC 3.2.1.17, muramidase, N-acetylmuramide glycanhydrolase; systematic name peptidoglycan N-acetylmuramoylhydrolase) is an antimicrobial enzyme produced by animals that forms part of the innate immune system. It is a glycoside hydrolase that catalyzes the following process: Hydrolysis of (1→4)-β-linkages between N-acetylmuramic acid and N-acetyl-D-glucosamine residues in a peptidoglycan and between N-acetyl-D-glucosamine residues in chitodextrinsPeptidoglycan is the major component of gram-positive bacterial cell wall. This hydrolysis in turn compromises the integrity of bacterial cell walls causing lysis of the bacteria. Lysozyme is abundant in secretions including tears, saliva, human milk, and mucus. It is also present in cytoplasmic granules of the macrophages and the polymorphonuclear neutrophils (PMNs). Large amounts of lysozyme can be found in egg white. C-type lysozymes are closely related to α-lactalbumin in sequence and structure, making them part of the same glycoside hydrolase family 22. In humans, the C-type lysozyme enzyme is encoded by the LYZ gene.Hen egg white lysozyme is thermally stable, with a melting point reaching up to 72 °C at pH 5.0. However, lysozyme in human milk loses activity very quickly at that temperature. Hen egg white lysozyme maintains its activity in a large range of pH (6–9). Its isoelectric point is 11.35. The isoelectric point of human milk lysozyme is 10.5–11.

1. lysozyme

   Lysozyme is an enzyme that is found in various bodily fluids such as tears, saliva, and mucus, and plays a vital role in the immune system by breaking down the cell walls of certain bacteria, thus, aiding in fighting against bacterial infections. It was first discovered in 1922 by Alexander Fleming. In addition to its natural occurrence, lysozyme is also used in food industry for its antimicrobial properties.

1. Lysozyme

   Lysozymes, also known as muramidase or N-acetylmuramide glycanhydrolase, are glycoside hydrolases. These are enzymes that damage bacterial cell walls by catalyzing hydrolysis of 1,4-beta-linkages between N-acetylmuramic acid and N-acetyl-D-glucosamine residues in a peptidoglycan and between N-acetyl-D-glucosamine residues in chitodextrins. Lysozyme is abundant in a number of secretions, such as tears, saliva, human milk, and mucus. It is also present in cytoplasmic granules of the polymorphonuclear neutrophils. Large amounts of lysozyme can be found in egg white. C-type lysozymes are closely related to alpha-lactalbumin in sequence and structure, making them part of the same family. In humans, the lysozyme enzyme is encoded by the LYZ gene.
