Merck, M9901-50KU, Mutanolysin from Streptomyces globisporus ATCC 21553

General description
Mutanolysin from Streptomyces globisporus consists of two main lytic enzymes and may be a useful agent for dental caries control.
Application
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.
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 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.
Physical form
Lyophilized powder containing Ficoll® and sodium succinate buffer salts
Other Notes
One unit will produce a ΔA₆₀₀of 0.01 per minute at pH 6.0 at 37 °C in a 1 mL volume using a suspension of Streptococcus faecalis cell wall as substrate.
