- An enzyme hydrolyzing 1,4-β links between N-acetylmuramic acid and N-acetyl-d-glucosamine, and thus destructive to cell walls of certain bacteria; present in tears and some other body fluids, in egg white, and in some plant tissues; used in the prevention of caries and in the treatment of infant formulas. SYN: mucopeptide glycohydrolase, muramidase.
* * *ly·so·zyme 'lī-sə-.zīm n a basic bacteriolytic protein that hydrolyzes peptidoglycan and is present in egg white and in saliva and tears called also muramidase
* * *n.an enzyme found in tears and egg white. It catalyses the destruction of the cell walls of certain bacteria. Bacterial cells that are attacked by lysozyme are said to have been lysed.
* * *ly·so·zyme (liґso-zīm) [EC 126.96.36.199] an enzyme of the hydrolase class that catalyzes the hydrolysis of specific glycosidic linkages in peptidoglycans and in chitin. The enzyme occurs in saliva, tears, egg white, and many animal fluids and catalyzes the breakdown of some bacterial cell walls.
