A 9387 is an inhibitor of Tn3-encoded resolvase protein binding at the res site.
A9387 is an inhibitor of the Tn3 Resolvase, which promotes site-specific recombination reactions between two directly repeated recombination sites. Several inhibitors have been isolated that inhibit this event. A9387 inhibits the binding of resolvase to the res site[1].
