"Complete sequence of Dechloromonas aromatica RCB.";
Submitted (AUG-2005) to the EMBL/GenBank/DDBJ databases.

Comments

FUNCTION: 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.
CATALYTIC ACTIVITY: 3-carboxy-2-hydroxy-4-methylpentanoate + NAD⁺ = 3-carboxy-4-methyl-2-oxopentanoate + NADH.
COFACTOR: Binds 1 magnesium or manganese ion per subunit (By similarity).
PATHWAY: Amino-acid biosynthesis; L-leucine biosynthesis; L-leucine from 3-methyl-2-oxobutanoate: step 3/4 .
SUBUNIT: Homodimer (By similarity).
SUBCELLULAR LOCATION: Cytoplasm (By similarity).
SIMILARITY: Belongs to the isocitrate and isopropylmalate dehydrogenases family. LeuB type 1 subfamily.
