Acetolactate Synthase (ALS)

Acetohydroxyacid synthase

Acetohydroxyacid synthase (ALS), a thiamine diphosphate-dependent enzyme, can condense either two pyruvate molecules to form acetolactate for synthesizing Lvaline and L-leucine or pyruvate with 2-ketobutyrate to form acetohydroxybutyrate for synthesizing L-isoleucine. Because the key reaction catalyzed by acetohydroxyacid synthase in the biosynthetic pathways of branched-chain amino acids (valine, leucine, and isoleucine) exists in plants, fungi, archaea, and bacteria, but not in animals, acetohydroxyacid synthase becomes a potential target for developing novel herbicides and antimicrobial compounds.

    Herbicide safener-4
    		Inhibitor
    Herbicide safener-4 (Compound I-15) is a Herbicide safener, improving the herbicide resistance of crops without reducing the herbicidal effect on targeted weed species. Herbicide safener-4 competitively binds to the ALS active site with Mesosulfuron-methyl (HY-126987). Herbicide safener-4 enhances GSH (HY-D0187), GST, CYP450, POD, SOD and ALS activity in plants.
