| 3.4.24.75 | additional information | Staphylococcus simulans | lysostaphin exhibits a high degree of antistaphylococcal bacteriolytic activity, being inactive against bacteria of all other genera. The cell-wall degrading activity of lysostaphin is primarily due to a glycylglycine endopeptidase activity. Staphylococcus simulans biovar staphylolyticus peptidoglycan is resistant to the hydrolytic activity of lysostaphin, since the cells produce a resistance factor that causes the incorporation of Ser residues into the third and fifth positions of the cell wall cross bridges | ? | - |
