Active Native Staphylococcus staphylolyticus Lysostaphin

• Cat.No.: Lysostaphin-91S
• Product Overview: Native Lysostaphin was purified from Staphylococcus staphylolyticus. Protein 50-70 % by biuret.

Specification

• Description: Lysostaphin is a lytic enzyme isolated from a bacterial culture of Staphylococcus staphylolyticus, which lyses Staphylococcus species, including S. aureus. Lysostaphin has hexosaminidase activity (specific for the glucosaminyl-muramic acid bond of the bacterial carbohydrate backbone, but does not react with S. aureus), amidase activity, and endopeptidase activity, which cleaves polyglycine cross-links in the cellular wall of Staphylococcus species.
