Characteristics of the protein coding sequence
Acetohydroxy acid synthase
EN
Acetolactate synthase (ALS) catalyzes the first common step in the biosynthesis of the essential amino acids isoleucine, leucine, and valine.

Native ALS is normally inhibited by sulfonylurea herbicides. However a naturally occurring mutation causes the production of an altered form of ALS (designated SuRB) that is insensitive to inhibition by sulfonylurea herbicides.
