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 oxopentanoate.
CC       {ECO:0000255|HAMAP-Rule:MF_01033}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(2R,3S)-3-isopropylmalate + NAD(+) = 4-methyl-2-oxopentanoate
CC         + CO2 + NADH; Xref=Rhea:RHEA:32271, ChEBI:CHEBI:16526,
CC         ChEBI:CHEBI:17865, ChEBI:CHEBI:35121, ChEBI:CHEBI:57540,

CC         Rule:MF_01033};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01033};
CC       Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01033};
CC       Note=Binds 1 Mg(2+) or Mn(2+) ion per subunit. {ECO:0000255|HAMAP-
CC       Rule:MF_01033};
CC   -!- PATHWAY: Amino-acid biosynthesis; L-leucine biosynthesis; L-leucine
CC       from 3-methyl-2-oxobutanoate: step 3/4. {ECO:0000255|HAMAP-
CC       Rule:MF_01033}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01033}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01033}.
CC   -!- SIMILARITY: Belongs to the isocitrate and isopropylmalate
CC       dehydrogenases family. LeuB type 1 subfamily. {ECO:0000255|HAMAP-
CC       Rule:MF_01033}.
