Application

Mutanolysin has been used in a study to assess lysing and generating protoplasts of dairy streptococci. It has also been used in a study to investigate the conversion of group B streptococci to protoplasts. It provides gentle cell lysis for the isolation of easily degradable biomolecules and RNA from bacteria. It has been used in the formation of spheroplasts for isolation of DNA.

Biochem/physiol Actions

Mutanolysin is an N-acetylmuramidase. Like lysozyme, it is a muralytic enzyme that cleaves the β-N-acetylmuramyl-(1→4)-N-acetylglucosamine linkage of the bacterial cell wall polymer peptidoglycan-polysaccharide. Its carboxy terminal moieties are involved in the recognition and binding of unique cell wall polymers. Mutanolysin lyses Listeria and other Gram-positive bacteria such as Lactobacillus and Lactococcus.

General description

Mutanolysin from Streptomyces globisporus consists of two main lytic enzymes and may be a useful agent for dental caries control.
