Acetolactate synthase isozyme 3 small subunit
Branched-chain-amino-acid aminotransferase
Acetolactate synthase isozyme 1 small subunit
Acetolactate synthase isozyme 1 large subunit
acetohydroxybutanoate synthase / acetolactate synthase
acetolactate synthase / acetohydroxybutanoate synthase
Ammonia + Chloride ion + Pyruvic acid → 3-Chloro-D-alanine + Water
(S)-2-Acetolactate + Acceptor → Carbon dioxide + Diacetyl + Reduced acceptor
3-Chloro-D-alanine + Thioglycolate → Chloride ion + S-Carboxymethyl-D-cysteine
Acetolactate synthase isozyme 3 large subunit
3-chloro-D-alanine + Thioglycolate ↔ Chloride ion + Hydrogen Ion + S-Carboxymethyl-L-cysteine
Hydrogen Ion + 2 Pyruvic acid → (S)-2-Acetolactate + Carbon dioxide
(R)-2,3-Dihydroxy-isovalerate → Isovaleric acid + Water
Isovaleric acid + L-Glutamic acid → L-Valine + Oxoglutaric acid
(S)-2-Acetolactate + Hydrogen Ion + NADPH → (R)-2,3-Dihydroxy-isovalerate + NADP
L-Valine (→) Transport: Escherichia coli, Cytosol to Escherichia coli, Periplasmic Space
