Beschreibung

General description

Chemical structure: coumarin-glycoside

Application

Novobiocin is used to study heat shock protein inhibition and to produce positively supercoiled plasmid DNA. It is an inhibitor of bacterial DNA gyrase and eukaryotic DNA topoisomerase. It also is an inhibitor of retrovirus RNA-dependent DNA-polymerase.

Für die Produktion von positiv superspiralisierter Plasmid-DNA. Inhibitor von bakterieller DNA-Gyrase und eukaryotischer DNA-Topoisomerase. Inhibitor von RNA-abhängiger DNA-Polymerase aus Retroviren.

Biochem/physiol Actions

Novobiocin inhibits DNA synthesis by inhibiting bacterial DNA gyrase targeting the GyrB subunit of the enzyme involved in energy transduction. Novobiocin acts as a competitive inhibitors of the ATPase reaction catalysed by GyrB . It is also a Hsp90 inhibitor . Antimicrobial spectrum: Gram-positive bacterial.

Wirkungsweise: Hemmt die DNA-Synthese durch Hemmen des Enzyms Topoisomerase II.
Antimikrobielles Spektrum: Grampositiv, bakteriell.
