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