The oxygenase reaction of acetolactate synthase

Biochemistry, 1993
In addition to the physiological reactions catalyzed by acetolactate synthase, it supports an oxygen-consuming side reaction. Although the synthase and oxygenase activities are activated to somewhat different extents by various metals (Mn2+, Mg2+, Ca2+, Co2+, Zn2+, Ni2+, Cd2+, Cu2+, Ba2+, Al3+), the modest degree of these differences (at most 6-fold ...

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.

Acetolactate Synthase Inhibitors

2002
Acetolactate synthase (ALS; EC 4.6.3.8, also referred to acetohydroxy acid synthase; AHAS) is the first common enzyme in the biosynthetic pathway to the branched-chain amino acids; valine, leucine and isoleucine (Fig. 1). The pathway exists in plants and microorganisms such as bacteria, fungi and algae.

Roles of Histidine Residues in Tobacco Acetolactate Synthase

Biochemical and Biophysical Research Communications, 2001
Acetolactate synthase (ALS) catalyzes the first common step in the biosynthesis of valine, leucine, and isoleucine in plants and microorganisms. ALS is the target of several structurally diverse classes of herbicides, including sulfonylureas, imidazolinones, and triazolopyrimidines.

Role of Tryptophanyl Residues in Tobacco Acetolactate Synthase

Biochemical and Biophysical Research Communications, 1999
Acetolactate synthase (ALS) catalyzes the first common step in the biosynthesis of valine, leucine, and isoleucine. ALS is the target of three classes of herbicides, the sulfonylureas, the imidazolinones, and the triazolopyrimidines. Five mutants (W266F, W439F, W490F, W503F, and W573F) of the ALS gene from Nicotiana tabacum were constructed and ...

Intraspecific variability of the acetolactate synthase gene

Weed Science, 2004
Common ragweed and common cocklebur plants were collected at two sites each in Illinois, Minnesota, and Ohio to analyze intraspecific variability of the gene encoding acetolactate synthase (ALS). A 385-nucleotide fragment within the coding sequence ofALSwas compared among 24 plants of each of these two species from the six locations.
