Description

Biochem/physiol Actions

Lysozymes participates in the defense mechanism. It has the ability to stimulate catalysis by bringing steric stress in the substrates.[1]

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.[1]

Other Notes

One unit will lyse 0.6 μg of Micrococcus lysodeikticus per minute by turbidimetric detection at 600 nm when suspended in buffer at pH 6.2 at 25 °C.

Physical form

Lyophilized from 50 mM sodium acetate, pH 6.0, with 100 mM NaCl

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.[2]
