General description
Mutanolysin from Streptomyces globisporus consists of two main lytic enzymes and may be a useful agent for dental caries control. [1]
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.
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
Preparation Note
Prepared from M 9901
Other Notes
One unit will produce a ΔA600 of 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.
