Biochem/physiol Actions RU7 is a selective inhibitor of bacterial β-clamp interaction with DNA polymerase POL III, and an inhibitor of a DNA polymerase sliding clamp. Sliding clamps are proteins which function with diverse DNA polymerases, repair factors, and cell cycle-control proteins. RU7 binds to the peptide-binding pocket of the β-clamp and selectively inhibits Pol III, compared with Pol II and Pol IV. |
