Aplicación

Proporciona una lisis celular suave para el aislamiento de biomoléculas y ARN fácilmente degradables de bacterias. Se ha utilizado en la formación de esferoplastos para el aislamiento del ADN.
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.

Acciones bioquímicas o fisiológicas

La mutanolisina es una N-acetilmuramidasa. Al igual que la lisozima, es una enzima muralítica que rompe el enlace β-N-acetilmuramil-(1→4)-N-acetilglucosamina del polímero de la pared celular bacteriana peptidoglucano-polisacárido. Sus restos carboxi terminales están implicadas en el reconocimiento y la unión de polímeros de pared celular únicos. Mutanolisina lisa Listeria y otras bacterias grampositivas como Lactobacillus y Lactococcus.

Group B streptococci, refractory to previously tested muralysins under physiological conditions, were successfully converted to protoplasts by use of a recently describede N-acetyl muramidase, mutanolysin, derived from a streptomycete. Purified enzyme was effective, but crude preparations, although degrading cell walls
