Description

Inhibits DNA synthesis by inhibiting the enzyme Topoisomerase II. Novobiocin Sodium Salt, MP Biomedicals is an antibiotic produced by Streptomyces nieveus. It is active against gram-positive bacteria. It is also a Hsp90 inhibitor 3.

Novobiocin inhibits DNA synthesis by inhibiting bacterial DNA gyrase targeting the GyrB subunit of the enzyme involved in energy transduction. It acts as a competitive inhibitor of the ATPase reaction catalysed by GyrB 2. Uses include:

  • For the production of positively supercoiled plasmid DNA
  • Inhibitor of bacterial DNA gyrase and eukaryotic DNA topoisomerase
  • Inhibitor of retrovirus RNA-dependent DNA-polymerase
  • To study heat shock protein inhibition
