General description

Chemical structure: coumarin-glycoside

Application

Coumermycin A1 is an aminocoumarin antibiotic used to study processes such as DNA replication, transcription, and recombination that involve DNA topoisomerase II activity. It has been used to treat Staphylococcus aureus endocarditis in the rat model and to study the effect of coumermycin A1 on the expression of 67 fusions in Salmonella typhimurium. .

Biochem/physiol Actions

Coumermycin A1 inhibits DNA Gyrase which thereby inhibits cell division in bacteria.

Many secondary metabolites of clinical importance have been isolated from different Streptomyces species.

During the biosynthesis of the streptomycete aminocoumarin antibiotics novobiocin and the dimeric coumermycin A(1), the bicyclic coumarin scaffold is C-methylated adjacent to the phenolic oxygen. The SAM-dependent C-methyltransferases NovO and CouO have been heterologously expressed and purified from Escherichia coli

The last stages of assembly of the aminocoumarin antibiotics, clorobiocin and coumermycin A(1), which target the GyrB subunits of bacterial DNA gyrase, involve enzymatic transfer of the pyrrolyl-2-carbonyl acyl group from a carrier protein (CloN1/CouN1) to the 3'-OH of the

Drug-dependent dissociation or association of cellular receptors represents a potent pharmacologic mode of action for regulating cell fate and function. Transferring the knowledge of pharmacologically triggered protein-protein interactions to materials science will enable novel design concepts for stimuli-sensing smart hydrogels.
