Mutanolysin from Streptomyces globisporus ATCC 21553

Purified Mutanolysin SAE0092 undergoes strict quality control testing to ensure the absence of detectable levels of contaminating DNA using 35 cycles PCR amplification of 16S and 18S rDNA using universal primer sets.
Mutanolysin is a muralytic enzyme, suitable for usage in isolation of nucleic acids, from Gram-positive bacteria (e.g. Listeria, Lactobacillus, Lactococcus),⁽⁸⁾ and also from other bacteria that are difficult to lyse with lysozyme only.

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 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.

Suitable for difficult-to-lyse samples.

Microbial DNA free, minimizing DNA contamination from reagents in workflow.

Suitable for the isolation of nucleic acids from Gram-positive bacteria, including Listeria, Lactobacillus, and Lactococcus.

Lyophilized powder containing Ficoll^® and sodium succinate buffer salts

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.
