Recombinant mutanolysin

A&A Biotechnology is proud to offer recombinant mutanolysin expressed in bacteria. We are first to produce recombinant version of this enzyme worldwide. Our recombinant mutanolysin exhibits superior purity and affordable price, compared to native alternative products available from other vendors. Enzyme is safe, being a product originating from organism recognized by U.S Food and Drug Administration as GRAS (Generally Recognized as Safe).

General description

Mutanolysin (EC (N-acetylmuramidase) is a muralytic enzyme that cleaves the β-N-acetylmuramyl-(1→4)-N-acetylglucosamine linkage of the bacterial cell wall peptidoglycan-polysaccharide. Its carboxy terminal moieties are involved in the recognition and binding of unique cell wall structures abundant in many gram-positive bacteria.


Recombinant mutanolysin effectively digests cell wall of particulary resistant to lysis bacteria.

Including but not limited to: Streptococcus, Lactobacillus, Lactococcus and Listeria.

Recombinant mutanolysin and lysozyme synergism

Mutanolysin lytic activity may differ substantially when lysing various, even closely related, bacteria. The lysis effectiveness depends on peptidoglycan cell wall structure and bacteria growth conditions. It is especially important issue to be considered when processing environmental samples. For some hard-to-lyse microorganisms the application of mutanolysin and lysozyme mixture may drastically increase the DNA/RNA yield. Please see below the synergistic effect of lytic activities of recombinant mutanolysin and lysozyme mixture.
For supplementing lysozyme application we recommend Lysozyme (cat. # 1005-10 or 1005-50).
