Yzym-LYS FOOD

-- Lysozyme Food Grade

Yzym-LYS FOOD is a series of powder-type Lysozyme (also called as Muramidase or N-acetylmuramide glycanohydrlase), derived either from bacterial fermentation or from egg-white extraction. Lysozyme is 129 amino acid residues enzyme (EC 3.2.1.17), which occurs naturally in plant and animal tissues and in secretions such as tears, saliva and mucus. Egg-white sourced lysozyme contains total protein 3.4% - 3.5%, it is a stable protein and a typical representative of the lysozyme class. It functions by catalyzing the hydrolysis of 1,4-β-linkages between N-acetylmuramic acid and N-acetyl-D-glucosamine residues in peptidoglycans and between N-acetyl-D-glucosamine residues in chitodextrins.
