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:0000256|RuleBase:RU004445}.
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 ChEBI:CHEBI:57945; EC=1.1.1.85;
CC Evidence={ECO:0000256|RuleBase:RU004445};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|RuleBase:RU004445};
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000256|RuleBase:RU004445};
CC Note=Binds 1 Mg(2+) or Mn(2+) ion per subunit.
CC {ECO:0000256|RuleBase:RU004445};
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000256|ARBA:ARBA00001936};
CC -!- PATHWAY: Amino-acid biosynthesis; L-leucine biosynthesis; L-leucine
CC from 3-methyl-2-oxobutanoate: step 3/4.
CC {ECO:0000256|RuleBase:RU004445}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|ARBA:ARBA00011738,
CC ECO:0000256|RuleBase:RU004445}.
CC -!- SIMILARITY: Belongs to the isocitrate and isopropylmalate
CC dehydrogenases family. {ECO:0000256|ARBA:ARBA00007769}.
