| Hazard Information | Back Directory | [Uses]
Lysostaphin from Staphylococcus simulans has been used in a study to assess molecular cloning, sequencing, and expression of lytM, a unique autolytic gene of Staphylococcus aureus. It has also been used in a study to investigate the sequence analysis of a Staphylococcus aureus gene encoding a peptidoglycan hydrolase activity. | [General Description]
Chemical structure: peptide | [Biochem/physiol Actions]
Lysostaphin is a zinc endopeptidase with a molecular weight of approximately 25 kDa. Because lysostaphin cleaves the polyglycine cross-links in the peptidoglycan layer of the cell wall of Staphylococcus species it has been found useful for cell lysis and also as a potential anti-microbial therapeutic. pH Optimum for activity: ~7.5 | [in vivo]
Lysostaphin (5 mg/kg, intravenous injection, once daily for 3 consecutive days) effectively clears systemic Staphylococcus aureus (MSSA) infections in CF-1 mice[2].
Lysostaphin (50 mg/kg, intravenous injection, single dose) effectively clears Staphylococcus aureus (MSSA and MRSA) infections from the kidneys, spleen, and liver, but is not superior to repeated lower doses[2].
Lysostaphin (1 mg/kg, intravenous injection, once daily for 3 consecutive days) combined with Oxacillin (HY-B0925A) achieves the same antibacterial effect with a lower concentration of Lysostaphin. When combined with Vancomycin, low-dose Lysostaphin (1 mg/kg) similarly shows enhanced efficacy against MRSA[2]. | Animal Model: | Systemic infection model in CF-1 mice induced by methicillin-susceptible Staphylococcus aureus (MSSA) and methicillin-resistant Staphylococcus aureus (MRSA)[2] | | Dosage: | 1, 5, 25, 50 mg/kg | | Administration: | Intravenous injection (i.v.), single high-dose administration: 25 mg/kg or 50 mg/kg intravenous injection, single dose; Once daily administration: 1 or 5 mg/kg, once daily for 3 days. | | Result: | Cleared MSSA from the blood and organs of mice (5 mg/kg for 3 days).
Cleared MSSA and MRSA from the kidneys, spleen, and liver (A higher single dose of 50 mg/kg).
Improved effectiveness and allowed reduction of the lysostaphin dose to 1 mg/kg for MRSA infections (Combined with Oxacillin (HY-B0925A) or Vancomycin (HY-B0671)). |
