ALS_ss_C is the C-terminal half of a family of proteins which are the small subunits of acetolactate synthase. 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]. [1]. 9197540. Identification of an acetolactate synthase small subunit gene in. two eukaryotes.. Duggleby RG;. Gene. 1997;190:245-249.

This family of domains generally have a regulatory role. ACT domains are linked to a wide range of metabolic enzymes that are regulated by amino acid concentration. Pairs of ACT domains bind specifically to a particular amino acid leading to regulation of the linked enzyme. The ACT domain is found in: D-3-phosphoglycerate dehydrogenase EC:1.1.1.95 Swiss:P08328, which is inhibited by serine [1]. Aspartokinase EC:2.7.2.4 Swiss:P53553, which is regulated by lysine. Acetolactate synthase small regulatory subunit Swiss:P00894, which is inhibited by valine. Phenylalanine-4-hydroxylase EC:1.14.16.1 Swiss:P00439, which is regulated by phenylalanine. Prephenate dehydrogenase EC:4.2.1.51 Swiss:P21203. formyltetrahydrofolate deformylase EC:3.5.1.10, Swiss:P37051, which is activated by methionine and inhibited by glycine.

Acetolactate synthase is a heterodimeric thiamine pyrophosphate enzyme with large and small subunits. One of the three isozymes in E. coli K12 contains a frameshift in the large subunit gene and is not expressed. acetohydroxyacid synthase is a synonym.
