Application

Lysozyme from human neutrophils has been used in the checkerboard method for establishing a synergy between peptidomimetic 1 and immune effector molecules against E. coli.

Biochem/physiol Actions

Lysozymes participates in the defense mechanism. It has the ability to stimulate catalysis by bringing steric stress in the substrates.

General description

Lysozyme is abundantly found in animal and plant kingdoms. It is a natural food preservative and also found to be present in specific bacterial cell walls. Lysozyme is usually present in tears, milk, urine and saliva.
