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

생화학적/생리학적 작용
Mutanolysin cleaves the β-N-acetylmuramyl-(1→4)-N-acetylglucosamine linkage of the bacterial cell wall polymer peptidoglycan-polysaccharide. It lyses Listeria and other gram positive bacteria such as Lactobacillus and Lactococcus.
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.

Streptococcus pyogenes (Group A Streptococcus; GAS) commonly causes pharyngitis in children and adults, with severe invasive disease and immune sequelae being an infrequent consequence. The ability of GAS to invade the host and establish infection likely involves subversion of host

Gram-negative bacteria are surrounded by a cell envelope that comprises an outer membrane (OM) and an inner membrane that, together, delimit the periplasmic space, which contains the peptidoglycan (PG) sacculus. Covalent anchoring of the OM to the PG is crucial

Group B streptococci, refractory to previously tested muralysins under physiological conditions, were successfully converted to protoplasts by use of a recently describede N-acetyl muramidase, mutanolysin, derived from a streptomycete. Purified enzyme was effective, but crude preparations, although degrading cell walls

In mammals, cyclic dinucleotides (CDNs) bind and activate STING to initiate an antiviral type I interferon response. CDNs and STING originated in bacteria and are present in most animals. By contrast, interferons are believed to have emerged in vertebrates; thus
