ID   2.2.1.6
DE   acetolactate synthase.
AN   acetohydroxyacid synthase.
AN   acetohydroxy acid synthetase.
AN   acetolactate pyruvate-lyase (carboxylating).
AN   acetolactic synthetase.
AN   alpha-acetohydroxyacid synthase.
AN   alpha-acetohydroxy acid synthetase.
AN   alpha-acetolactate synthase.
AN   alpha-acetolactate synthetase.
CA   H(+) + 2 pyruvate = (2S)-2-acetolactate + CO2.
CC   -!- The reaction shown is in the pathway of biosynthesis of valine.
CC   -!- The enzyme can also transfer the acetaldehyde from pyruvate to
CC       2-oxobutanoate, forming 2-ethyl-2-hydroxy-3-oxobutanoate, also known
CC       as 2-aceto-2-hydroxybutanoate, a reaction in the biosynthesis of
CC       isoleucine.
CC   -!- Formerly EC 4.1.3.18.
