Description_x000D_ General description_x000D_ Mutanolysin from Streptomyces globisporus consists of two main lytic enzymes and may be a useful agent for dental caries control._x000D_ Application_x000D_ 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._x000D_ Biochem/physiol Actions_x000D_ 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._x000D_ Unit Definition_x000D_ 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._x000D_ Physical form_x000D_ Lyophilized powder containing Ficoll and sodium succinate buffer salts_x000D_ Preparation Note_x000D_ Prepared from M 9901_x000D_ Other Notes_x000D_ View more information on enzymes for complex carbohydrate analysis at www.sigma-aldrich.com/enzymeexplorer
