leuA | 2-isopropylmalate synthase; Catalyzes the condensation of the acetyl group of acetyl-CoA with 3-methyl-2-oxobutanoate (2-oxoisovalerate) to form 3-carboxy-3- hydroxy-4-methylpentanoate (2-isopropylmalate); Belongs to the alpha-IPM synthase/homocitrate synthase family. LeuA type 1 subfamily. (532 aa) | ||||
leuB | 3-isopropylmalate dehydrogenase; Catalyzes the oxidation of 3-carboxy-2-hydroxy-4- methylpentanoate (3-isopropylmalate) to 3-carboxy-4-methyl-2- oxopentanoate. The product decarboxylates to 4-methyl-2 oxopentanoate. (363 aa) | ||||

leuD-2 | 3-isopropylmalate dehydratase small subunit; Catalyzes the isomerization between 2-isopropylmalate and 3- isopropylmalate, via the formation of 2-isopropylmaleate. Belongs to the LeuD family. LeuD type 1 subfamily. (200 aa) | ||||
W5S_3952 | Acetolactate synthase. (554 aa) | ||||
W5S_3953 | Acetolactate synthase, isozyme I, small subunit. (97 aa) | ||||
ilvC | Ketol-acid reductoisomerase (NADP(+)); Involved in the biosynthesis of branched-chain amino acids (BCAA). Catalyzes an alkyl-migration followed by a ketol-acid reduction of (S)-2-acetolactate (S2AL) to yield (R)-2,3-dihydroxy-isovalerate. In the isomerase reaction, S2AL is rearranged via a Mg-dependent methyl migration to produce 3-hydroxy-3-methyl-2-ketobutyrate (HMKB). In the reductase reaction, this 2-ketoacid undergoes a metal-dependent reduction by NADPH to yield (R)-2,3-dihydroxy-isovalerate. (492 aa) | ||||
ilvA | L-threonine dehydratase; Catalyzes the anaerobic formation of alpha-ketobutyrate and ammonia from threonine in a two-step reaction. The first step involved a dehydration of threonine and a production of enamine intermediates (aminocrotonate), which tautomerizes to its imine form (iminobutyrate). Both intermediates are unstable and short-lived. The second step is the nonenzymatic hydrolysis of the enamine/imine intermediates to form 2- ketobutyrate and free ammonia. In the low water environment of the cell, the second step is accelerated by RidA. (514 aa) | ||||
ilvD | Dihydroxy-acid dehydratase; Belongs to the IlvD/Edd family. (616 aa) | ||||
ilvE | Branched-chain-amino-acid aminotransferase; Acts on leucine, isoleucine and valine. Belongs to the class-IV pyridoxal-phosphate-dependent aminotransferase family. (308 aa) | ||||
W5S_4383 | Acetolactate synthase, isozyme II, small subunit. (86 aa) | ||||
W5S_4384 | Acetolactate synthase. (548 aa) |
