This domain is also found at the C-terminal of D-3-phosphoglycerate dehydrogenase, which are closely related [4-7]. Acetolactate synthase small subunit (ILVH) is the regulatory subunit of acetohydroxyacid synthase (AHAS), an enzyme hat catalyses the first step in the biosynthesis of the three branched-chain amino acids [4-7].

Acetolactate synthase is a tetrameric enzyme, containing probably two large and two small subunits, which catalyses the first step in branched-chain amino acid biosynthesis. This reaction is sensitive to certain herbicides [1].
