Description

• General description: Mutanolysin from Streptomyces globisporus consists of two main lytic enzymes and may be a useful agent for dental caries control. [1]
• Application: Mutanolysin has been used in a study to assess lysing and generating protoplasts of dairy streptococci. [2] It has also been used in a study to investigate the conversion of group B streptococci to protoplasts. [3] 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.
• Unit Definition: 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.
• Physical form: Lyophilized powder containing Ficoll® and sodium succinate buffer salts
