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.

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

Many secondary metabolites of clinical importance have been isolated from different Streptomyces species. As most of the natural producers remain difficult to handle genetically, heterologous expression of an entire biosynthetic gene cluster in a well characterised host allows improved possibilities

Phosphorylation of the alpha (α) subunit of the eukaryotic initiation factor 2 (eIF2) at serine 51 is an important mechanism of translational control in response to various forms of environmental stress. In metazoans, eIF2α phosphorylation is mediated by four kinases

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.
