Sunflower resistance to acetolactate synthase-inhibiting herbicides [PDF]

Pesquisa Agropecuária Tropical, 2012
Sunflower is very sensitive to herbicides applied in post-emergence to control broad-leaf weeds. Researchers have developed herbicide-resistant genotypes to imidazolinone herbicides.

Comparison of ?-acetolactate synthase and ?-acetolactate decarboxylase in Lactococcus spp. and Leuconostoc spp. [PDF]

Biotechnology Letters, 1994
Cell-free extracts of Leuconostoc and Lactococcus species were tested for their alpha-acetolactate synthase and alpha-acetolactate decarboxylase activities. In Leuconostoc mesenteroides subsp. cremoris, Leuconostoc mesenteroides subsp. mesenteroides and Leuconostoc lactis, the Km of alpha-acetolactate synthase for pyruvate was close to 10 mM whereas it

Identification and evaluation of novel acetolactate synthase inhibitors as antifungal agents. [PDF]

Antimicrob Agents Chemother, 2013
ABSTRACT High-throughput phenotypic screening against the yeast Saccharomyces cerevisiae revealed a series of triazolopyrimidine-sulfonamide compounds with broad-spectrum antifungal activity, no significant cytotoxicity, and low protein binding.

HERBICIDES THAT INHIBIT ACETOLACTATE SYNTHASE [PDF]

Frontiers of Agricultural Science and Engineering, 2022
Herbicides are an essential pillar in modern agricultural practice. They are used to selectively reduce the growth of weeds in crops and natural environments. Early weed mitigating chemicals date back to Roman times and include substances as simple as table salt, sulfuric acid and carbon bisulfide.

An in vivo Acetolactate Synthase Assay

Weed Technology, 1995
A method was developed and tested for in vivo assay of acetolactate synthase (ALS). The method used foliar application of 1,1-cyclopropanedicarboxylic acid (CPCA) to inhibit ketol-acid reductoisomerase, the enzyme immediately following ALS in biosynthesis of branched-chain amino acids, thereby causing accumulation of acetolactate.

Crystallization of the FAD-independent acetolactate synthase ofKlebsiella pneumoniae [PDF]

Acta Crystallographica Section D Biological Crystallography, 2002
Leucine and valine are formed in a common pathway from pyruvate in which the first intermediate is 2-acetolactate. In some bacteria, this compound also has a catabolic fate as the starting point for the butanediol fermentation. The enzyme (EC 4.1.3.18) that forms 2-acetolactate is known as either acetohydroxyacid synthase (AHAS) or acetolactate ...

Efficient production of α-acetolactate by whole cell catalytic transformation of fermentation-derived pyruvate

Microbial Cell Factories, 2019
Background Diacetyl provides the buttery aroma in products such as butter and margarine. It can be made via a harsh set of chemical reactions from sugarcane bagasse, however, in dairy products it is normally formed spontaneously from α-acetolactate, a ...

Identification of an acetolactate synthase small subunit gene in two eukaryotes

Gene, 1997
Acetolactate synthase catalyses the first step in branched-chain amino acid biosynthesis. The bacterial enzyme contains two large and two small subunits but there is only limited and circumstantial evidence for a small subunit in the eukaryotic enzyme.

Physiological basis for isoxadifen-ethyl induction of nicosulfuron detoxification in maize hybrids. [PDF]

PLoS ONE, 2017
Isoxadifen-ethyl can effectively alleviate nicosulfuron injury in the maize. However, the effects of safener isoxadifen-ethyl on detoxifying enzymes in maize is unknown.

Synthetic evolution of herbicide resistance using a T7 RNAP–based random DNA base editor

Life Science Alliance, 2022
A chimeric fusion of T7 RNAP and deaminase edits the DNA under the T7 promoter in plant cells. It directs the continuous synthetic evolution of OsALS to produce variants with herbicide resistance.
