Mutanolysin (EC 18.104.22.168) (N-acetylmuramidase) is a muralytic enzyme that cleaves the β-N-acetylmuramyl-(1->4)-N-acetylglucosamine linkage of the bacterial cell wall polymer
peptidoglycanpolysaccharide. Its carboxy terminal moieties are involved in the recognition and binding of unique cell wall structures aboundant in many gram-positive bacteria.
Recombinant mutanolysin effectively lyses particularly problematic bacteria, like:
Streptococcus, Lactobacillus, Lactococcus, Listeria.
Recombinant Mutanolysin and lysozyme activity is synergistic. Using Mutanolysin and lysozyme mixture leads to increased yield of bacteria
