Light yellow Muramidase Lysozyme Powder Enzyme Feed Additive
Szym-LYS20FO is a powder-type Lysozyme (also called as Muramidase or
N-acetylmuramide glycanohydrlase), derived from egg-white with
total protein 3.4% - 3.5%. Lysozyme is 129 amino acid residues
enzyme (EC 22.214.171.124), which occurs naturally in plant and animal
tissues and in secretions such as tears, saliva and mucus.
Egg-white lysozyme 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.

Enzyme preparations belong to protein, which may induce
sensitization and cause allergic type reactions in sensitized
individuals. Prolonged contact may cause minor irritation for skin,
eyes or mucous membrane of nose, so any direct contiguity with
human body should be avoided. If irritation or allergic response
for skin or eyes develops, consult a doctor.
