Coumermycin A1

DNA gyrase inhibitor
BML-GR317-0005 5 mg Inquire for pricing
Do you need bulk/larger quantities?
Inhibits supercoiling activity of gyrase by binding to the gyrase B domain – but more importantly is a novel cell permeable dimerizing ligand for gyrase B fusion proteins. Has been used to dimerize a variety of signaling proteins such as Raf1, JAK2, Tyk and L-selectin.
