This entry represents the ACT domain found at the N-terminal of acetolactate synthase small subunit from Escherichia coli and similar sequences. 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].	Domain
A	PF00389	D-isomer specific 2-hydroxyacid dehydrogenase, catalytic domain (2-Hacid_dh)	D-isomer specific 2-hydroxyacid dehydrogenase, catalytic domain	This family represents the largest portion of the catalytic domain of 2-hydroxyacid dehydrogenases as the NAD binding domain is inserted within the structural domain.
