Discovery and Structural Basis of Zoledronic Acid as a Potent SPS-Targeting Herbicide.
Solanesyl diphosphate synthase (SPS) is essential for plastoquinone-9 (PQ-9) biosynthesis and has emerged as a promising target for herbicide discovery. The commercial SPS herbicides bind to the dimer interface of the protein; however, substrate-competitive SPS inhibitors are still rare, particularly in agronomically r...
