[Study of acetyl-CoA-synthetase from staphylococcus aureus]
Biokhimiia (Moscow, Russia)
|March 1, 1975
Summary
Researchers isolated and partially purified Acetyl-CoA-synthetase from Staphylococcus aureus 209-P cells. Enzyme activity was found to depend on cell culture age and acetate presence, with specific inhibitors identified.
Area of Science:
- Biochemistry
- Enzymology
- Microbiology
Context:
- Investigating enzymes crucial for bacterial metabolism.
- Understanding the biochemical pathways in Staphylococcus aureus.
- Characterizing enzymes involved in acetate metabolism.
Purpose:
- To isolate and partially purify Acetyl-CoA-synthetase from Staphylococcus aureus 209-P.
- To determine kinetic parameters (Km values) for substrates: acetate, CoA, and ATP.
- To identify inhibitors of Acetyl-CoA-synthetase activity.
- To assess the influence of cell culture age and acetate availability on enzyme activity.
Summary:
- Acetyl-CoA-synthetase was successfully isolated and partially purified from Staphylococcus aureus 209-P.
- Kinetic parameters, including Km values for acetate, CoA, and ATP, were determined.
- The enzyme's activity was inhibited by p-Chloromercuribenzoate and monoiodoacetate.
- Enzyme activity demonstrated a dependency on the age of the bacterial culture and the presence of acetate in the growth medium.
Impact:
- Provides a foundational understanding of Acetyl-CoA-synthetase function in Staphylococcus aureus.
- Characterization of the enzyme aids in potential therapeutic target identification.
- Insights into acetate metabolism regulation in bacteria.
- Establishes a basis for further biochemical and genetic studies of this enzyme.
