3-isopropylmalate dehydratase large subunit; Catalyzes the isomerization between 2-isopropylmalate and 3- isopropylmalate, via the formation of 2-isopropylmaleate.

Rv0189c, (MTCI28.28c), len: 575 aa. Probable ilvD,dihydroxy-acid dehydratase, similar to many e.g. ILVD_LACLA|Q02139 dihydroxy-acid dehydratase (dad) from Lactococcus lactis (subsp. lactis) (Streptococcus lactis) (570 aa), FASTA scores: opt: 1605, E(): 0, (46.0% identity in 561 aa overlap). Also similar to ML2608|MLCL622.06c|O06069|ILVD_MYCLE dihydroxy-acid dehydratase from Mycobacterium leprae (564 aa). Contains PS00886 Dihydroxy-acid and 6-phosphogluconate dehydratases signature 1. Belongs to the ILVD / EDD family. Cofactor: binds 1 4FE-4S cluster (potential).

Branched-chain amino acid transaminase IlvE; Catalyzes the reversible transfers of an amino group from glutamate to the alpha-ketoacid of the respective amino acid in the final step in the biosynthesis of branchedchain amino acids. The amino acids can be ranked in the following order with respect to their efficiency as amino donor: Leu > Ile > Val. Belongs to the class-IV pyridoxal-phosphate-dependent aminotransferase family.

Probable acetaldehyde dehydrogenase (acetaldehyde dehydrogenase [acetylating]); Catalyzes the conversion of acetaldehyde to acetyl-CoA, using NAD(+) and coenzyme A. Is the final enzyme in the meta-cleavage pathway for the degradation of aromatic compounds.

Probable acetolactate synthase (small subunit) IlvN (acetohydroxy-acid synthase) (AHAS) (ALS); Catalyzes the conversion of 2 pyruvate molecules into acetolactate in the first common step of the biosynthetic pathway of the branched-amino acids such as leucine, isoleucine, and valine. Belongs to the acetolactate synthase small subunit family.

Acetolactate synthase (large subunit) IlvB1 (acetohydroxy-acid synthase); Catalyzes the conversion of 2 pyruvate molecules into acetolactate in the first common step of the biosynthetic pathway of the branched-amino acids such as leucine, isoleucine, and valine. Also involved in condensing pyruvate and 2-ketobutyrate to form 2-aceto-2- hydroxybutyrate.

Probable acetolactate synthase IlvG (acetohydroxy-acid synthase)(ALS); Catalyzes the conversion of 2 pyruvate molecules into acetolactate in the first common step of the biosynthetic pathway of the branched-amino acids such as leucine, isoleucine, and valine.

Probable acetohydroxyacid synthase IlvX (acetolactate synthase); Catalyzes the conversion of 2 pyruvate molecules into acetolactate in the first common step of the biosynthetic pathway of the branched-amino acids such as leucine, isoleucine, and valine.

Acetyl-/propionyl-coenzyme A carboxylase alpha chain; This protein carries two functions: biotin carboxyl carrier protein and biotin carboxyltransferase.
