Acetolactate Synthase (ALS)

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.

Cat. No. Product Name Effect Purity
  • HY-119737
    Chlorsulfuron
    Chlorsulfuron blocks the biosynthesis of the amino acids valine and isoleucine in plants. Chlorsulfuron completely alleviates herbicide-induced growth inhibition. The site of action of Chlorsulfuron is the enzyme acetolactate synthase[1].
  • HY-B1876S
    Nicosulfuron-d6
    Nicosulfuron-d6 is the deuterium labeled Nicosulfuron[1]. Nicosulfuron is a selective herbicide belonging to the sulfonylurea family. Nicosulfuron is commonly used as a post-emergence herbicide to protect maize crops from weeds. Nicosulfuron inhibits acetolactate synthase (ALS) enzyme activity[2].
  • HY-B1847
    Terbuthylazine
    Terbuthylazine is an inhibitor of acetolactate syntase (ALS), is a selective herbicide.

    Imazamox 99.69%
    Imazamox (CL29926) is a systemic herbicide that inhibits the production of acetolactate synthase (ALS) in plants with high selectivity, high activity, safety and broadspectrum activity, which would then inhibit plant growth and ultimately lead to plant death[1][2].
  • HY-B1847S1
    Terbuthylazine-d5
    Terbuthylazine-d5 is the deuterium labeled Terbuthylazine[1]. Terbuthylazine is an inhibitor of acetolactate syntase (ALS), is a selective herbicide[2].

    Imazamox-13C,d3 is the 13C- and deuterium labeled Imazamox. Imazamox (CL29926) is a systemic herbicide that inhibits the production of acetolactate synthase (ALS) in plants with high selectivity, high activity, safety and broadspectrum activity, which would then inhibit plant growth and ultimately lead to plant death[1][2].
  • HY-B0865
    Pyrazosulfuron-ethyl 99.63%
    Pyrazosulfuron-ethyl, one of the acetolactate synthase inhibiting herbicides in the sulphonylurea family, has been widely used to control weed growth in commercial cereal, soybean, and vegetable fields[1].
  • HY-B0869A
    Bispyribac sodium
    Bispyribac sodium is a selective, systemic and post emergent herbicide used to eradicate grasses and broad leaf weeds. Bispyribac sodium is also an acetolactate synthase (ALS or known as AHAS) inhibitor[1].
